yeah, the temp fix i’ve found is to make a copy of the sequence stored in the usd file (double click the sequence in the usd to load it, use the wrench icon to save it to a new name in your content folder), make a new camera, parent it underneath your usd camera, and drag that camera into sequencer
now and then i’ve been able to use the usd camera directly, but it wasn’t reliable, this hacky hack works
