Hey. Please dont hate me because I make things in Sketchup, I just don't like Blender and find the Sketchup programme easier to use than Blender. I have made a few vehicle/ideas and I have read the vehicle creation wiki page carefully. But this is all based in blender. If I was to make vehicles in Sketchup, would all the steps in the wiki page work in the same way?
I would say no, but then again I don't know too much, however in this thread there was useful link for sketchup user: https://www.beamng.com/threads/sketchup-lods-collision-mesh.34927/
sketchup makes it extremely difficult (but not impossible) to create the correct poly flow for BeamNG. Bad poly flow leads to bad game mesh. Entire program really isnt setup for doing game modelling. It is possible though. @Bakasan does it.
