So I'm processing some megascans assets coming in via bridge, here is the before and after, I'm basically just adding in proxy purpose meshes which is just a polyreduced version of the original.

Before:




After:



(maybe this can be done in a cleaner way so any comments welcome there*)

The issue I'm having is that when I write this out to a USD file and load it into the stagemanager, I seem to lose the ability to change the variant from within the stage manager, only outside of it using the 'set variant' node. You can see the variants listed, maybe its a bug in the stage manager?

Dude! I'm also trying to get megascans working properly. It seems like it should work great when you import to USD stage but everything is broken

Yep that is how the stage manager works. You bring in your assets with the stage manager and then you use the set variant node to set the variant.
