Hello!
I have created a simple animated sphere in Houdini with a basic material that has the base color mapped to a primvar derived from the position of the sphere. All works well in Houdini and the sphere changes color as it is moving according to the animation, but once this is saved to usd and exported to UE, the base color is lost. The primvar also seems to not be animated once in Unreal.
My question is if Primvar are supposed to be supported in MaterialX in Unreal and if not when can it be expected?
