if I try to load the lib manually:

previous snapshot version (3.3.2-1) works fine

Hey @wizzardo,

The problem was the support for KHR_draco_mesh_compression added with #773. I assumed that the Draco library would be statically linked into the Assimp shared library, but turns out it's a separate binary. The next 3.3.2 snapshot will bundle both shared libraries in the Assimp native jar.

Thanks!

LWJGL 3.3.2 snapshot 3 is now available and Assimp is working again.
