Failed To Create MDL Module

I am trying to import materials for use in an IsaacSim model and have had many issues with Nvidia’s MDL files. I am trying to use both the vMaterials2 library and the vMaterials library that comes with the Isaac-Sim linux install. When attempting to add the MDL material to an object, for most materials I get the following error “Failed to create MDL material” followed by the path to the material. It doesn’t impact every material, but it is the vast majority. I’ve also noticed some don’t appear to render correctly. Ruby for example has no red tint.

Hi David,

Please stay tuned. We will have a new release in early June, in which the material importation has improved a lot.
Let us know then if you still have this issue.
