the problem :
when I choose the ASSIMP3 backend
I can load an .obj file, but it looks bad (problem on the faces indexes ?).
(see attached patch)

notes :
the OBJ backend works fine with .obj files
ASSIMP3 works fine with .blend files
pd 0.49
ubuntu 18.04
gem from git

it is strange because some models seems to work, and some others don't...
so it may be related to how the .obj files are made ?
will try to investigate a bit further this weekend...

just a quick note: the problem in the example is the Highr5 object (the 2nd from left). all the other problems are directly related to rendering this object.
