3d Model Import Question

My three would be:

  • simplify geometry - use fewer segments in circles, arcs, and shapes created from them by FollowMe tool. Replace heavily detailed geometry by simpler geometry with an image. You will probably need to redraw all or parts of the model to do this
  • delete invisible internal details if present
  • reduce texture sizes to the minimum needed for your intended use
