how to access another geometry from Karma shader? Jan. 12, 2021, 12:01 p.m.

Being able to access the renderable USD scene graph would be a great Karma feature. It would be a competitive advantage from my POV. My guess is that it's probably hard to implement efficiently...

Prune USD prims via SOP Modify? Dec. 20, 2020, 3:42 p.m.

Thanks for the suggestion, Configure Prim seems like the best way at the moment. Some kind of masking usd attribute that gets read by SOP Import might be useful, though.

Prune USD prims via SOP Modify? Dec. 19, 2020, 12:23 a.m.

Let's say I have a character animation I've imported for lookdev and I want to replace the eye geometry by creating new polygons in a SOP Modify. The original geometry is made up of 5 meshes, but my new geometry is only 3 meshes. Is there a way I can conveniently prune or deactivate the extra meshes from the USD tree once I've made my new geometry? It would be ideal to do all of this within the SOP logic, where the decision to prune or not might lie.

I guess I could always generate an attribute that gets imported into LOPs that I can then use to prune with.
