I’ve just made some tests: ps_4_0 Is it possible to use an RWStructuredBuffer in a vertex shader in Unity? Most I have read indicates it should be possible, but I am not having any success. Then you may call tex2Dlod and give it the LOD manually. Skip to content. ) will work correctly with shadow maps. I am currently creating a Unity Texture2D object and specifying the format as RGB565 then populating it using the LoadRawTextureData function. Load(int3(input. 0). ddx [in] Rate of change of the surface geometry in the x direction. TexCd. You just use standard tex2d with the correct texture state objects set and you'll get mipmap filtering. To avoid the trouble, the only best solution that I have seen on the web is to use tex2Dlod (but if you have a better solution I take).

Copy link WilliamOChai commented Apr 7, 2022. x * width, input. 6 //FREE\\ File-Upload. and without blending between different texture scale ( the process that most bloom effect take), the edge will be too sharp. Best. Performance Guidelines gives some guidance on Hi, I need to unify some amount of shader code under DX11 HLSL using Unity macros like SAMPLE_TEXTURE2D instead of tex2D. \nIndirect Lighting brightens objects that are exposed to a certain 'light source' you may specify in the parameters below. Color components (like red, for example) range from 0. The shader always samples from mip level 0. 1. \nThis approach takes directional information into account and simulates Motivation, goal. Often it’s better to change the solution to use Tex2DLod I'm trying to interpolate between integer pixel coordinates instead of between 0-1, because I'm using point sampling, so I'm not interested in fractions of pixels, but the texture coordinates are still coming into the pixel shader as float2 even though the data type is int2. CS50 is the quintessential Harvard (and Yale!) course. Programming Interface describes the programming interface. color = view0. 0 as tex2Dlod is a Shader model 3. Share. Any ideas?

According to the Nvidia GPU programming guide, tex* intrinsics should work (page 54): "NOTE: In ForceWare 61. has anybody found a solution to have Unity Account You need a Unity Account to shop in the Online and Asset Stores, participate in the Unity Community and manage your license portfolio. fxsub at main · Hoyotoon/MMDGenshin Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Surface Shaders Unity’s code generation approach that makes it much easier to write lit shaders than using low level vertex/pixel shader programs. The short version is GPUs calculate What is the difference between tex2D() and SAMPLE_TEXTURE2D? I am trying to create a four corner pin post processing effect, and my lines come out curved with The shader uses tex2Dlod to sample the displacement texture, and I’ve found this doesn’t work on my android device (which is on GLES 2. Improve this answer. If the texture doesn’t have mip-maps then you can obviously skip it all together and just use tex2D. Hi, I’m trying to write a shader that will create an outline around a sprite. I'm a Python Programmer who recently started with PyCuda because I need to write a custom filter for image processing. already tested in all chapters i didnt found any bugs, and in all dlcs desesperate escape and lost in nightmare without problems. 頂点シェーダーでテクスチャを読み込みときは、tex2Dlodを使いますのでご注意ください！ 注意点：テクスチャの設定でWrap ModeをClampに I was having issues with my installation of FFXIV, so I decided to do a clean install. depthTextureMode = DepthTextureMode. y) the tex2D function carries out an (bicubicbilinear) interpolation taking the neighbour pixel values into account weighted by their distance from the sample point. ret tex2D(s, t, ddx, ddy) Parameters. tex. This function samples a texture using the sampler specified by s, the texture coordinates in t, the x gradient in ddx, and tex2Dlod in Unity shaders, does it work? I'm trying to sample from explicit mipmap levels in the shader, but it looks impossible. 0) and texture () on newer versions. tex2D(tex, X, Y); Besides this, Can you tell me how texture memory using texture to access an array, and how this transform looks like? opencv; cuda; textures; cuda-arrays; Share. float textureSample = tex2D(_myTexture, uv_values); which is something I did before, and got curious on how exactly is it that the sample of a texture returns a float. Return Value. Alkher March 7, 2017, 8:25am 26. Automate any Name. However, you don't have to compute the level of detail yourself! tex2D actually offers an overload taking dx and dy which are the aforementioned derivatives, tex2D(s, uv) being equivalent to hi there, at the moment i am working on a terrain decal shader which i would like support tiling texture atlases. May also use pre computed derivatives if those are provided. Close. Think of tex2D as a function that returns a color. \nThis approach takes directional information into account and simulates I could use a little help here, it seems that tex2Dlod ALWAYS returns (0, 0, 0), no matter what gridPos is (and this changes, I've checked). Q&A. Developer Tools. DirectX 11 (DX11) HLSL syntax in Shaders ShadowMap是比较流行的实时阴影实现方案，原理比较简单，但真正实现起来还是会遇到很多问题的，我这里主要记录下实现方式先看效果凹凸地形上也有阴影实现原理ShadowMap技术是从灯光空间用相机渲染一张RenderTexture，把深度值写入其中所以称之为深度图，在把接受阴影的物体从模型空间转换到灯光 The tex2D function usually returns a float in the range of [0. I don't really know Cg, but if tex2D is equivalent to what it was in older HLSL then you can't use it anything except for a pixel shader. Write better code with AI Security. From my research it seems tex2Dlod is not supported (bar using an extension). Afterwards, I attempted to reinstall Reshade, which I did over a year ago and did not remember the process of getting it to work very well. 1 GShade is a heavily modified fork of ReShade and features numerous improvements as well as a selectively-unlocked depth buffer for specific online games. As far as I know, I am doing everything as I should, so I am really interested in knowing where I The bug number is 3295173. - Mortalitas/GShade-Shaders I'm trying to use tex2dlod and only ever getting black colors back. 0, tex2Dproj和tex2D这两个功能几乎相同。 唯一的区别是，在对纹理进行采样之前， tex2Dproj将输入的UV xy坐标除以其w坐标。这是将坐标从正交投影转换为透视投影。例如 以下段代码的返回值是相同的. The issue should be fixed in the next CUDA release after 11. 5 and which one rounds up or down to the As stated the tex2D function calculates the texture’s mip level during the fragment shader stage. 4. SCR. \nThis approach takes directional information into account and simulates GameDev. Current hardware can only sample textures in the vs if they're a specific format. y * height, 0)); Even though what you're doing is functionally equivalent, I've run into strange issues in the past which were resolved by using inputs rather than outputs that are initialised from input data That’s not strictly true, linear memory can be bound to a 2D texture using cudaBindTexture2D() and read using tex2D() (this is so called pitch-linear texturing), although the performance is not always as good as 2D texturing from CUDA arrays. md at master · keijiro/unity-tex2dlod-example Sample Texture 2D LOD Node Description. Sample() method that is equivalent to this tex2D (HLSL reference) - Select the mip level - Win32 apps | Microsoft Learn You can solve this by either not using derivatives at all (ie. tex2Dproj - performs a texture lookup with projection in a given sampler. Nsight Compute. Render To Vertex Buffer (R2VB) •“Render to VB” = “Render to texture and re- interpret texture data as VB” •Very general approach –Allows “aliasing” textures to VB and fetching 2D texture linearly –Can even alias data types 2D texture Vertex stream They represent the same operation, but Sample is what it's called in D3D10 and newer versions of HLSL, while tex2D is what it's called in D3D9 HLSL, and NVIDIA's (defunct) Cg language. The texture assigned to the material needs to have mipmaps before the shader runs. Shader here Shader "RW Structured Buffer" { Properties { _MainTex ("Texture", 2D) = "black" {} } Subshader { Pass { CGPROGRAM #pragma vertex vertex_shader #pragma fragment pixel_shader #pragma target 5. This is not valid, as UV derivatives don’t exist in the Vertex Shader. Programming Model outlines the CUDA programming model. Otherwise, I get some unexpected behavior: if, for example, I want to fetch element A(13,12), and I attempt to retrieve it using tex2D(tex, row + 0. WilliamOChai opened this issue Apr 7, 2022 · 3 comments Comments. - keijiro/unity-tex2dlod-example Unityにて、頂点シェーダーで参照したいテクスチャをTex2DlodSampleにアタッチ、フラグメントシェーダーで参照したいテクスチャをTextureにアタッチすればOKです。. We’re trying to deform vertices according height data stored in a texture. And because on some GPUs using tex2Dgrad() causes it to make assumptions about whether or not it can reuse the cached mip level across the entire quad. Old. The ray is sampled in the direction form entrance to leaving point. 😵💫 I’m sure there’s a way to do this as numerous engines That’s not strictly true, linear memory can be bound to a 2D texture using cudaBindTexture2D() and read using tex2D() (this is so called pitch-linear texturing), although the performance is not always as good as 2D texturing from CUDA arrays. Hardware Implementation describes the hardware implementation. I found tex2D and it seems very elegant to me for handling padding and out of range problems. Automate any grabbing ___. Why? Because it’s sending 3 times as much information out of the shader to the hardware texture unit. 0) are nice about this, they automatically determine the texture overload based on "3. 5 when it is undefined is to use the tex2Dgather function instead. float existingDe In OpenGL, what is the difference between GL_DEPTH_COMPONENT and GL_DEPTH_STENCIL? I have looked around and have been unable to find a clear explanation. 999×498 539 KB. The thing is I use SampleLevel not tex2D nor texlod. Hello folks, I hope you're having a good one. Type Description. #802. Thus I use tex2Dlod(float2Coord, 0, 0) instead of tex2D(float2Coord), and the problem is solved. has anybody found a solution to have Using tex2D in the Vertex Shader. Dynamically Uniform Expressions and Uniform Control Flow" from the GLSL specs I linked above elaborates on how different instances of the shader are executed at the same time, and the flow is "uniform" only when the same instruction is Item Description; s [in] The sampler state. 0 spec only requires tex2Dlod in the vertex shader. Use the LOD input to adjust the level of detail of the sample. \nThis parameter represents the power of the angle falloff. main. CalculateLevelOfDetail() does not generate mipmaps, it returns the mip level the GPU would have calculated for the tex2D() function such that it and tex2Dlod() using the returned value as the LOD are identical. You need to sample an explicit mip level instead; for example, use tex2Dlod (tex, float4(uv,0,0)). Leave feedback. After trying to compile your shader (on my nVidia) I got this in the logs:. 8. \nThe Fresnel Coefficient is set to 0 to match most surfaces. 0, \n. My problem is that I am very confused about how I can pass data to the cuda kernel. 0f (which was the value of both of the constants anyway) the loops now run. Reload to refresh your session. However, using tex2d directly in a Vertex shader doesn’t work. 3 program, I’m using tex2D(texture<T, 2, cudaReadModeElementType>, float, float) which was declared deprecated in texture_fetch_functions. Thanks. We always intended to expose it but we rarely had the need. Improve this question. Do you know how well tex2dLoD is supported on Android hardware. I use OpenGL and the VS and PS shader model 3_0 cause higher versions do not seem to be However tex2Dgrad() is itself is usually slower than tex2D() or even tex2Dlod(). also there are disabled lines (with "//" ) in original code that you need to remove form the ported version. Hi, i'm having a couple of issues with the tex2D-functions when using mipmaps. RU Stata MP 15. 3. Also tex2Dlod is used here instead of tex2D because it's on the vertex shader side, where no screen-space derivative of the coordinate is available to determine the mipmap level If I artificially reduce the texture size to something tiny, it’s somewhere between the tex2Dlod() and tex2Dgrad() methods in pure shader execution cost because it is a more complex shader. FINAL NOTES First of all, 30FPS isn’t an option. tex2Dgather allows you to read texture data from a 2D texture using integer coordinates instead of floating-point coordinates, which is what I'm trying to access a texture in my vertex shader. There’s a sample “simplePitchLinearTexture” in the SDK. tex2Dlod() and tex2Dgrad() will work fine inside one.

Contribute to zchee/cuda-sample development by creating an account on GitHub. When sampling a texture in a pixel shader, the required lod level is picked automatically by tex2D because it can see how much the uv coordinates vary between two adjacent pixels. Unity lets you choose from pre-built render pipelines, or write your own. An example of the usage of tex2Dlod in surface shaders. I create a ComputeBuffer on the CPU side and fill it with some vertex positions, then use Running the tex2D in the vertex shader (tex2Dlod is the one that works in Vertex). xy); Sampling levels is now done like this: float4 col = tex2Dlod(Samp, float4(In. I dont really understand the way that the texture reference object is utilized by host and device code. hmmm. Could the texture be wrong? I'm loading a RAW grayscale image as input and I create the texture using D3DFMT_R16F format. without a so strong crhomatic aberration. tex2Dbias - 2D texture lookup with bias and optional texel offset.

Does tex2d() automatically do the compare? According to the Nvidia GPU programming guide, tex* intrinsics should work (page 54): "NOTE: In ForceWare 61. However, as Nathan Reed and other members have pointed out, texture formats that are not normalized may return It’s not supported in 4_9_1. By channeling the UV2 coordinates way trought the pipeline (vertex-> hull → tesselation → domain → geometry → fragment) and finally sampling them inside the fragment shader like below I made very good results. I was getting the impression from forum posts that the only way to accomplish this is to force unity to run in opengl and use “ #pragma glsl”, even though im on windows? I do this all the time in dx with hlsl, and it works without a problem, i thought unity ran with dx on windows, so why isnt this possible? I created a bug for that (TTP 327033 UE4: RENDRING: Expose Texture2dGrad to material expressions). I don’t know how to implement this either. Sign in Product GitHub Copilot. Success! Thank you for helping us improve the quality of Unity Documentation. However, when I try to add an offset to the texture coordinate, the shader won’t compile. Name In/Out Template Type Kojack wrote:tex2D isn't compatible with vertex shaders.

LL, i want to ask which function can get the sass instruction TLD. 0. xy,level); 3/VVVV Related changes Those changes are not part of standard DirectX, but are also breaking changes compared to DirectX Hello, I’d like to ask if there is a possibility to sample a Texture2DArray in vertex shader? Normally, to sample a regular texture in vertex shader, I’d use tex2Dlod But since sampling Texture2DArray requires a macro (UNITY_SAMPLE_TEX2DARRAY), which encapsulates the regular tex2D used in fragment shaders, I can’t use it there. tex2Dlod can be faster because it doesn’t need to compute the mip-level to sample from using implicit derivatives. First, when using tex2D() with a biased ("MipLODBias = xyz") sampler If you pass an float4 it looks the same as tex2Dlod. What is the reason for this? Do I need to use tex2d() to sample the image? But when I use Intro. tex2D can't be used inside a vertex shader, so I tried tex2Dlod instead. Last edit: 6 years 11 months ago by crosire. As noted below, the sampler state you define in HLSL is not relevant to the vs profiles only fx. Hi! I made a simple character customization in MTA with CJ skin, bone_attach, and some custom models. It might seem strange, given what we’ve learned so far, to be using textures within the vertex shader, but it can certainly be helpful. 5f, col + 0. In compute shader, I use tex2dlod() to sample the texture, and the texture is not black. 5, out of tex2Dlod and tex2Dbias which one blurs between MIP levels 2 and 3 with a lerper of 0. \nHigher values restrict reflections to very flat angles. tex2D.

You can override the UV coordinates using the UV input and define a custom Sampler State using the Sampler input. Many shader code tutorials online are intended to be used in Unity’s Built-in Render Pipeline and might not work in the Universal Render Pipeline – They’ll either produce magenta errors or at least won’t be compatible with the SRP Batcher, which batches the setup between draw calls for each shader/material, so rendering many objects with that shader will In this case, you need to pass the UV coordinates (possibly extending SurfaceOutputStandard) and to use tex2Dlod instead of tex2D. Using tex2D in the Vertex Shader. Hello, I am trying to use _CameraDepthNormalsTexture to get normal and depths in a surface shader. What is the reason for this?

The troublesome code is below: void disp Using tex2D in the Vertex Shader. I'm trying to use tex2dlod and only ever getting black colors back. Tex2DGrad is quite slower on a lot of hardware than Tex2DLod (we have exposed). Things like “tex2Dlod” work but they push us over the edge into DX11 territory and we’re trying to remain DX9 compatible. What is wrong with the this code? The CG version of SampleLevel is tex2Dlod. as far as i am now, the shader either supports nicely tiling textures (using tex2Dlod) but no anisotropic filtering which looks pretty weired especially on terrains –*or it shows nicely filtered textures but seams (using tex2d). without lens distortion. It's just tex2D() that won't compile, and you can work round that by computing ddx() and ddy() outside the conditional and using tex2Dgrad(). Open comment sort options. The problem is that your if will be flattened (both executed, result of the wrong branch discarded), because you're using gradient functions like tex2D in one of your branches (). This is compounded by the fact that pix likes to crash quite a bit on my machine so I'm having some trouble debugging. However, the result of depthnormal is wrong. You should see the performance gain if you remove those functions from your branches or replace them with non-gradient functions like tex2Dlod or tex2Dgrad.

More info See in Glossary, Surface Shaders A streamlined way of writing shaders for the Built-in Render Pipeline. 0 where the former is the total absence of that color and the latter is full intensity. Depth; My bet is your variable has been optimized out by driver or the shader did not compile/link properly. tex2Dlod is supported in fragment profiles starting with fp40 and in vertex profiles starting with tex2D - performs a texture lookup in a given 2D sampler and, in some cases, a shadow comparison. At the moment I have the horrid solution of replicating all the code for each kernel with the only change being that the tex2D function makes use of a different texture reference, e. 0 capable hardware, it has support. Sample(S,float,int,float) Samples a texture with an optional value to clamp sample level-of-detail (LOD) values to. The function takes two additional coordinates; for this specific application, you can set both of them to zero: thickness = tex2Dlod (_LocalThickness, fixed4(uv, 0, 0)). In that case, the "indices" f and c should not be integers, but continuous values between the limits of each dimension. Here's the image that illustrates the issues: I guess the the left and right image in every row should look the same? Warning: Various shaders for ReShade (convolutions, gpu optical flow, and other image processing) - Touqai/brimsonFX Shader here Shader "RW Structured Buffer" { Properties { _MainTex ("Texture", 2D) = "black" {} } Subshader { Pass { CGPROGRAM #pragma vertex vertex_shader #pragma fragment pixel_shader #pragma target 5. Note that I am not using a Compute Shader. Here is the code: #if OPENGL #define SV_POSITION POSITION #define VS_SHADERMODEL vs_3_0 #define by switching between tex2D and tex2Dlod the border effect get less visible. But I’m stumped about how to do tex2DGrad, which is expecting DDX/DDY parameters, using SAMPLE_TEXTURE2D_LOD, which is expecting a Mip level. I hadn’t realized that those coordinates need to be normalized First, when using tex2D () with a biased ("MipLODBias = xyz") sampler the resulting mipmap differs between d3d9 and d3d11. What is a bit odd in this example is that the return value is an integer, which will make any linear interpolant piecewise constant anyway. It seems that CG does not like constants, since changing the constants in the loop to 16. This function return a color of a sampler texture at specified coordinates (like tex2D) but you can also specify the mip level to use. More info See in Glossary have some support for DirectX 11 / OpenGL Core The back-end Unity uses to support the latest OpenGL features on Windows, MacOS X and Linux. r; return col; what do i need to read up on / examples with Tex2D() that explains UNorm conversion? even if i tell the texture Type ‘Default’ and sRGB = true output is clearly banding and brighter when compared to RGBA input and Try using tex2Dlod, or. " I have a piece of HLSL code which looks like this: float4 GetIndirection(float2 TexCoord) { float4 indirection = tex2D(IndirectionSampler, TexCoord); for (half mip = indirection. Order of Tex2D in shader. 3+, which corresponds to OpenGL 3. A focused topic, but broadly applicable skills. \n; dst can accept a write mask. \$\endgroup\$ – *blah-blah-blah maniac* Posts: 552 Joined: Wed Apr 11, 2012 3:24 am Name. xy,0,level)); becomes float4 col = texture2d. 71 and I need something demonstrating how to transform my regular cuadMalloc()'ed array into the structures needed by the beforementioned tex2D* flavors. h(198).

If you only want to blur a screen aligned rectangle, then the best method is the former one. Suggestions are to go back to CUDA 11. I went to Microsoft docs to inspect the tex2D function documentation. What replaces it ? and how do I use it ? tex2Dlod - 2D texture lookup with specified level of detail and optional texel offset. Here's the image that illustrates the issues: I guess the the left and right image in every row should look the same? Warning: Depending on the texture properties, the value returned by tex2D may be linearly interpolated. No errors, no warnings either. You also need to add #pragma target 3. Otherwise it’s not great as the ES 2. with tweaked effect list for more realistic colors and constrast, with less colorfull palette, for resident evil 5.

Try using tex2Dlod, or. This doesn’t clarify anything to me solved. Suggest a change. There, it says (I quote): Return Value The value of the texture data. At each sample point (pos. The text was updated successfully, but these errors were encountered: Demanding, but definitely doable. Remove the "[unroll]" specifiers and replace the "tex2D" calls in the loop body with "tex2Dlod" (can't use gradient expressions in a dynamic loop) and it works. The code is as follows: float4 result = tex2Dlod(Tex, float4(uv, 0, 0)); However, after displaying the sampling results in Vision Pro, the scene appears black, so the sampling result is 0. throbax March 6, 2017, 2:58pm 21. g. I'm being silently ignored. net - RadioCapriDeel06. \nOriginal Schlick value: 5. 0 and is still available in CUDA 11. You switched accounts on another tab or window. has anybody found a solution to have Name. In a cuda 11. I’m facing a bit of a problem here. This is not valid, because UV derivatives don’t exist in the vertex Shader. Using a read-only StructuredBuffer does work. Shame on me. 0, 1. net is your resource for game development with forums, tutorials, blogs, projects, portfolios, news, and more. Unity What happens if you updated your vs like so: output. Top. Samples a Texture 2D and returns a Vector 4 color value for use in the shader. 71 and later, any texture instruction (tex2D, tex2Dlod, etc. tex2D - performs a texture lookup in a given 2D sampler and, in some cases, a shadow comparison. The shader uses tex2Dlod to sample the displacement texture, and I’ve found this doesn’t work on my android device (which is on GLES 2. May perform a shadow comparison if argument for shadow comparison is provided. Depth; with tweaked effect list for more realistic colors and constrast, with less colorfull palette, for resident evil 5. I figured I could use a displacement texture that I draw the deformation to and pass that texture to the shader, as I had seen in YouTube videos. cuda version: 11. 2. ddy [in] Rate of change of the surface geometry in the y direction. Demanding, but definitely doable. Does there exist an The next best solution is to use tex2Dgrad () instead of tex2D () or tex2Dlod (). tex2D(texture<T, 2, cudaReadModeElementType>, float, float) which was declared deprecated in texture_fetch_functions. RGBA16F, RGBA32F or, standard, RGBA8. Download Microsoft Edge More info about Internet You can solve this by either not using derivatives at all (ie.

Collection of general-purpose effects for the ReShade shader injector. Hello ! I wanted to ask whether the function texture in glsl is same as tex2d() in hlsl ? Are there any differences between the 2? Thanks in advance Share Sort by: Best. type "if statement" in d3dsdk, it says tex2D is indeed a "gradient instruction", for it defaltly load mipmaps by gradient. But When specifying say a LOD-bias of 2. or Explore the Zhihu column for free expression and writing on various topics of interest. Newer versions of GLSL (1. Sample (sampler##tex,coord) There’s a lot of HLSL code in there, and anything you find in there will guaranteed compile. supplying a constant LOD through tex2DLod rather than the tex2D) or by manually computing the derivatives outside of the loop, and supplying them explicitly. 5f), I get A(14,11). tex2Dfetch - performs an unfiltered texture lookup in a given sampler. vertexシェーダ内でテクスチャを参照する場合は tex2D の代わりに tex2Dlod を使用します。 tex2Dlod（ テクスチャ, float4（U値, V値, 0, w ＝（ lod 値の指定0~7 ）） This browser is no longer supported.

MultiMaterial is shader that allows composition of textures used in material from multiple layers of common textures via defined mask. From my research it seems The shader does not use any particular pragmas for any shader language, the line in question is a simple "fixed4 col = tex2Dlod(_TexMontage, float4(i. TextureDimension. 0]. What replaces it ? and how do I use it ? warning : functi Mip-maps are selected automatically to be used using a tex2D(s,t) operation. In order to do this I want to sample the pixels around the given pixel in the pixel shader. This function is meant to be used in pixel shader only as the rasterization will determine the UV coordinate screen space derivative (how much UV changes from one pixel to its neighbor). Render To Vertex Buffer (R2VB) •“Render to VB” = “Render to texture and re- interpret texture data as VB” •Very general approach –Allows “aliasing” textures to VB and fetching 2D texture linearly –Can even alias data types 2D texture Vertex stream (D3D11_TEX2D_UAV) Skip to main content. Creating an optimized tex2D function, again, I’m clueless. I'm playing with an fov of 90 at 1080 which is what I am most comfortable with but the only drawback is that the top and bottom of the screen are stretched. like so #define UNITY_DECLARE_TEX2D(tex) Texture2D tex; SamplerState sampler##tex #define UNITY_SAMPLE_TEX2D(tex,coord) tex. x,pos.
