I just rebuilt after enabling USD in cmake. I cannot redo the error. Is your build correct ?

Hello,
I am not building blender myself. I download the windows 10 x64 version from the nightly builds at https://builder.blender.org/download/
As I wrote, in Blender 2.82a USD works. In the current builds something is missing?!
It seams that in the 2.83alpha builds the USD Plugin is not included?

There does seem to be an issue with master.

2.82 release is fine:

Can confirm the issue but haven't looked deeper into it,, @Jesse Yurkovich (deadpin) 's test seems elegantly simple, perhaps we should include it in the unit tests?

I confirm: I can export from 2.82 but not from 2.83. I downloaded 2.83 alpha this morning. So do we need to download and install something besides Blender 2.83 alpha?

Jesse Yurkovich (deadpin) added a comment.Apr 6 2020, 11:22 PM

It was just fixed so you'll have to wait to download the new nightly build available in the next 4 hours or so.
