I have a setup that includes a primvar based switch in the shader (that has been assigned to an asset) to switch between different textures. The switch texture has been connected to both - the base color and displacement. Inside the instancer a random value has been assigned to the attribute. When the instancing method is set to point instancer the basecolor uses the primvar correctly but the displacement uses the first texture for all the instances. Swithcing the method to instanceable references works on both. I wonder if thats by design in the usd, a bug or im just doing something wrong?
