Now you can use this _MainTexInternal as if it was a 2D array in your shader. You need to specify the same in C#, and keep in mind this is global on the GPU. The register(u2) represents which internal gpu registrar to bind the data structure to.

So I’m’a show you how to UAV in unity shaders. It’s got such a cool range of possibilities, that you can even do dumb simple stuff like sample the shader’s color under your mouse cursor, from inside the shader, and write it from inside the shader to a struct that you can simultaneously read back in C#, with no need to iterate through pixels or have access to any textures or anything like that. This is great because it allows you to easily bake data onto mesh textures or atlasses while they’re being rendered to screen anyway. (For more reading look up UAVs (Unordered Access Views), SRV (Shader Resource Views), and shader Resource Binding registers.)īut with shader model 5.0 and d3d11 you can now do more or less the same in regular vertex fragment shaders. These can hold spatial information trees, distance fields, flow maps, points, meshes etc. You probably know that you can assign and write to render textures and 3D textures and even custom data buffers like RW Structured Buffers from Compute Shaders.
