public void SetTextureFromGlobal(int kernelIndex, string name, string globalTextureName);
public void SetTextureFromGlobal(int kernelIndex, int nameID, int globalTextureNameID);


kernelIndexFor which kernel the texture is being set. See FindKernel.
nameIDProperty name ID, use Shader.PropertyToID to get it.
nameName of the buffer variable in shader code.
globalTextureNameGlobal texture property to assign to shader.
globalTextureNameIDProperty 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.
