I'm trying to use Karma to bake but I want to bake multiple objects (that are already atlased)

Using this for how to bake -

It doesn't seem like it works for multiple object by default though?

I'm now trying a sop edit where I'm combining USD objects and trying to output them into a new USD that has them combined but I'm struggling to get multiple materials on geometry subsets working in USD though.

You can see the setup is two different USD prims get combined into one so they can be baked together, however I can't maintain the material seperation while keeping them a single prim mesh, I think I need to use geosubset but I can't seem to get it working.

I tried shop_materialpath as well as usdmaterialpath


Any tips would be really appreciated!
