Hi Andrew,
I think it will be good to have a sketchup importer or a exporter for those reasons :
-The free version of Sketchup don’t have .obj or .fbx exporter.
-There is some geometry issues at exportation with Sketchup for .fbx and .obj
-If I import my mesh and combine meshes, all materials are in the same mesh so it is difficult to find a material in this big list.
-If I import my mesh without combining, my groups and components are all separated, sometime even the faces.
-There is a problem with UV overlapping when building lights from models coming of Sketchup
Thank you
