Write to Texture3D using a Compute shader

I'm having some trouble getting my compute shader to output to a 3D texture. I managed a 2D texture just fine and as far as I can tell I have made all the nessessary changes for 3D so I'm at a bit of a loss as to how to proceed. The code is pretty simple, am I missing something? Thanks

Code (csharp):

1. public static class ComputeTexture
2. {
3.     public static RenderTexture Create(ComputeShader shader, int width, int height, int depth)
4.     {
5.         var texture = new RenderTexture(width, height, 0, RenderTextureFormat.ARGBFloat, RenderTextureReadWrite.Linear);
6.         texture.isVolume = true;
7.         texture.dimension = UnityEngine.Rendering.TextureDimension.Tex3D;
8.         texture.volumeDepth = depth;
9.         texture.enableRandomWrite = true;
10.      
11.         texture.Create();
12.  
13.         Fill(shader, texture);
14.  
15.         return texture;
16.     }
17.  
18.     public static void Fill(ComputeShader shader, RenderTexture texture)
19.     {
20.         int kernelHandle = shader.FindKernel("CSMain");
21.  
22.         shader.SetTexture(kernelHandle, "Result", texture);
23.         shader.Dispatch(kernelHandle, texture.width / 8, texture.height / 8, texture.depth / 8);
24.     }
25. }
26.  
27. #pragma kernel CSMain
28.  
29. RWTexture3D<float4> Result;
30.  
31. [numthreads(8,8,8)]
32. void CSMain(uint3 id : SV_DispatchThreadID)
33. {
34.     Result[id.xyz] = float4(1, 0, 0, 1);
35. }
36.  

 

Hey, have you found the solution? I have exactly the same problem, it just wont write for some reason

 

Unfortunately no, in the end I just did it on the cpu.

 

Ah, its a shame. Ill keep looking then, thanks for reply.

 

For me its Win7 x64, DX11, GTX 1050 TI. Unity 2017.2. Just tried with OpenGLES3, also didnt work. Also tried regular Texture3D, and that failed as well.

 

Not sure if this is the only issue, but the line

shader.Dispatch(kernelHandle, texture.width / 8, texture.height / 8, texture.depth / 8);

Should be

shader.Dispatch(kernelHandle, texture.width / 8, texture.height / 8, texture.volumeDepth / 8);
