• Current result: Vertex ridges remain stationary while texture highlights appear to move

Modifying the shader in Spector to use transformedUV seems to result in correct behavior, and it looks like this change could be made around line 325 of TextureBlock.ts, but I'm not sure if that's the right solution or might have unintended consequences in other shaders.
