Hi,
I just opened some old .mb file with a bush assets prepared for .usd export. I noticed it has OmniSurfaceLite material applied, when I export it as .usd and throw it to USD Composer it works well, however with newer Maya
Connector installed I cannot reproduce this, I am receing error and .mdl Module is missing.
Instead, I have to convert all my V-Ray materials to USD Surface and then convert them all again in USD Composer to OmniSurface…
