Closed redchillipadi closed 5 years ago

When saving a glTF file, blender is looking in the wrong directory for libextern_draco.so

Steps to reproduce the issue:

The log shows 

Read prefs: /home/adrian/.config/blender/2.80/config/userpref.blend
'/usr/bin/2.80/python/lib/python3.7/site-packages/libextern_draco.so' does not exist, draco mesh compression not available

The libextern_draco.so is found at /usr/share/blender/2.80/python/lib/python3.7/site-packages/libextern_draco.so

This is fixed by commit 71dc06ad5b30976cd4253f64c3ca811a08596718

According to https://docs.blender.org/manual/en/latest/advanced/blender_directory_layout.html the python installation directory can be stored in the LOCAL (/usr/bin) or SYSTEM (/usr/share/blender) directory. The existing code searched the LOCAL directory, but the library was stored under the SYSTEM directory.
