I made a test with an extra library (assimp - http://assimp.sourceforge.net/) to load new mesh formats inside wz.
It works great, lightweight and it's really easy to use with wz (twenty lines of code for the proto). Animation need more works to run but it should be possible to add.
list of supported formats is impressive : see https://github.com/assimp/assimp
Here a proto. (use the ImportEx operator)
note : if you download assimp binaries there is a bunch of all supported model files that you can test here.
