RVT Sample Parameter not working on Instances

When using RVT Sample Parameters node (mostly for blending), it works perfectly it we have it setup in the Main Material. But if we create a instance of that material, and change the RVT, it all turns to black.

Example:

  • Create material that uses RVT for blending;
  • It works perfectly on map A (that uses RVT A);
  • Now I want the same effect on map B (that uses RVT B);
  • If I change in the main material, it will work;
  • But if it’s changed via RVT Sample Parameter, on a Material Instance, it will return black;
