I'm using an .obj file to import an object made out of line segments. It has a list of vertices ('v' elements) followed by line definitions ('l' elements)
So a square would be
v 1 1 0
v 1 -1 0
v -1 -1 0
v -1 1 0
l 1 2 3 4 1
When I import this into Sketchfab I just get the line segments v1-v2 and v3-v4.
Is this a bug in the OBJ importer or is this something more fundamental to Sketchfab?
And even if I work around this bug by adding a line 'l 2 3 4 1' (to get the other segments), I'm having problems when I have multiple lines over 500 vertices. Any insights about this? I'm new to the Sketchfab community and for now only want to get this line model working and posted.
