Hello all,
so importing USD with materialX embedded materials will work with USD interchange and not USD legacy nor loading in a USD stage actor.
- Make sure the plugin Interchange OpenUSD is activated. When importing the USD you can check it is interchange if you get the interchange dialog window (cf. 2.)
- Make sure the render context is “mtlx” in the Translator settings
If some of you still have issues, I might ask some sample to try to reproduce.
