Prisim | Unreal Engine


Yeah I think the alembic streaming feature will be a massive bonus as when you’re working with tons of animation it’s a much cleaner workflow in the unreal sequencer as opposed to importing heaps of FBX files which can turn sequencer into an eye sore pretty quickly.

Hopefully USD would allow for round tripping but as I mentioned I can’t seem to load a usd created in unreal in other dcc’s. Probably user error though 🙂

So yeah if anyone knows how to export a useful usd file from unreal...

I managed to write out some usd files from Unreal with some xforms, lights and cameras. However it looks like it doesn't support exporting geometry. It is mentioned in the documentation so maybe there is a way, but even by looking at the code I didn't find a way to do it so far.

Also in 4.26 the default python version is 3.7 and some of the usd scripts are not working with Python 3.7. So to use some functions you either have to modify the Unreal USD python scripts or switch to Python 2.7

Is there any update on this?

No update from my side at the moment.
