How to import group with usd create component sop node? Aug. 28, 2026, 9:08 p.m.
The closest equivalent in LOPs/USD of SOP geometry groups, is GeomSubsets [www.sidefx.com]. You can turn primitive groups into geomsubsets, this is an option on the SOP Import/SOP CReate; points/edges aren't yet possible on the USD side (it's getting closer, I believe). Hope this helps!
Unable to adjust the camera focus plane in Karma / Solaris C Aug. 12, 2026, 1:56 p.m.
What are you Shift+LMB clicking in the scene? I can imagine if a parameter were locked on the node, that might interfere with the state adjusting the focus distance correctly? It sounds like a bug, but I'm unable to reproduce it in a simple scene.
[H22] SOP > USD workflow question Aug. 12, 2026, 1:49 p.m.
Yeah you use a SOP import to get the geometry into LOPs. The new nodes are just working to improve the UX for structuring scenes in SOPs before they end up in USD.
