| kernelIndex | For which kernel the texture is being set. See FindKernel. |
| nameID | Property name ID, use Shader.PropertyToID to get it. |
| name | Name of the buffer variable in shader code. |
| globalTextureName | Global texture property to assign to shader. |
| globalTextureNameID | Property name ID, use Shader.PropertyToID to get it. |
Set a texture parameter from a global texture property.
This function can either set a regular texture that is read in the
compute shader, or an output texture that is written into by the shader.
For an output texture, it has to be a RenderTexture with random write
flag enabled, see RenderTexture.enableRandomWrite.
Buffers and textures are set per-kernel. Use FindKernel to find kernel index by function name.
