Hi.

For Blender 3.1 please download our latest build with 3.10 Python BlenderUSDHydraAddon_1.0.92_3.10_Windows.zip

from blenderusdhydraaddon.

I have the same issue on Centos 7.9 Linux with blender 3.1.2 using python 3.10

find /usr/local/blender/ -name "*libpython*"
gives me:

not sure why it wants to import the libpython3.10.so.1.0 and not libpython3.10.a

any ideas?

thanks a lot and have a great weekend!

Try to run apt install libpython3.10.

from blenderusdhydraaddon.

why would i need to install this when i'm already inside of a 3.10 interpreter?

from blenderusdhydraaddon.

Because on Unix-like systems you very often don't have required packages.

Guys, is there a solution for that problem? Cannot use it on macOs 12.4 Monterey

There is a blender side issue that doesn't allow us to import USD libraries. We're trying to find another solution but there has to be a change on the blender side.
