I got this error when trying to use vMaterials 2 in SOLIDWORKS Visualize 2025:

"Error loading document: Glass_Dirty.mdl

MDL SDK library version 2023.0.2 does not match header version 2023.0.2.”

I just installed the program and made sure to select the complete install, such that the Material Exchange pre-requisite was installed.

Some vMaterials 2 work fine, inlcuding:

Aluminum (basic)
Brass (basic)

Copper - Aged
All the plastic textures

While others fail:
All aluminum derivative (scratched, knurled, hammered, etc.
All brass derivatives
Stainless steel
Leather
Fabric
Water

This isn’t a comprehensive list of what works or doesn’t, but these are the ones I have tested.

Any ideas on how to fix this issue?

The NVIDIA team recommended that I revert to a previous update of MDL Material Exchange (nvidia-vmaterials_2-nt-x86-64-2.2.1-367100.3961), which I did, but am still having issues loading some materials.

Any help is appreciated..
