USD.command - "/Applications/usdpython/USD.command ; exit;"

For some reason when i double click the USD.command tool terminal responds with "/Applications/usdpython/USD.command ; exit;" Anyone know why "; exit;" is being appended to the end and quitting? This is a fresh install and Ive never had this happen before, very very frustrating. Just spent the last 2 hours trying to adjust my PYTHONPATH etc etc and to get this thing working urggghhh. zsh is linking to python3.8.3.

Reality Composer - Behaviours across multiple scenes not working

Hi, I managed to get multiple scenes working by loading each one into the viewController but only one behaviour seems to be working for the first scene only and not the other scenes. There doesnt seem to be any code required to register the first behaviour via tap so Im not sure why the other taps wont work either for the other scenes? Many thanks

Maya - Alembic - USDZ

Cant seem to get animated alembic file out of Maya and animate in a finder window let alone as a usdz file.It seems easy enough to create an alembic cache in Maya and then import it back in without any problems there.But when I select the alembic cache in a finder window or preview, all I get is a single frame without animation. Do animations by default not auto play in a finder window? Does anyone know of a good previewer that will play Alembic animations easily on OSX?This is the first step for me to try to get the alembic to USDZ because even after using the xcrun command on the .abc file I still dont get any animations to show up in a usdz previewer. So there seems to be something wrong with the .abc file even though Maya has no issue with importing one and playing animations.Regards
