Is there any way to get LOP lights to OBJ?
I've tried exporting to usd, but obviously there is only a sop-level USD Import node and that doesn't work.

The idea is to get some lights out of Solaris for the fx dept to use with Mantra.

No tooling for that, but you can use the lop import object to fetch a transform, and use python expressions to drive parameters on the parented light. good luck with that usd python api though, what a nightmare.
