Select the Material you just created. 08), and the Description. 0; float3 v = normalize ( viewDir); v. This just makes the code easier to read and is more Description. SetGlobalColor ("Global_HeightFog_Color", heightFogColor); But then I still have to define each global variable in the outer-most shader graph and send it into the subgraphs, which is tedious. Each input needs to have a semantic specified for it: for example, POSITION input is the vertex position, and NORMAL is the vertex normal. I found that shaders in prefrontalcortex/UnityGLTF works in VisionOS. Shadows require a shader to have special passes to do shadow rendering (ShadowCaster & ShadowCollector; starting with 5. 0 devices cannot read from textures in the vertex shader, and do not have a function to sample a specific mip level even in the fragment shader. The process of creating a new Material and assigning it a Shader Graph shader is the same as that for regular shaders. I suspect this might be a Shader Graph issue, because, working in the editor implies it should work correctly on the device.
