I'm planning on making a medieval town in SketchUp to be imported into Unity but I know people have had trouble with SketchUp. I know how to fix the face orientation problem (where some faces would be flipped and appear transparent), and I also have the pro version meaning I can export as obj. 3ds. fbx. and many others. I also know how to use the group tool to prevent meshes from getting too redundant (see pic). However I know SketchUp creates meshes and texture maps differently than other programs and I'm wondering if this could lead to optimization problems. Any help would be appreciated, thanks.
