Hi all, I built the following items for my MTC map (https://trackmania.exchange/maps/52933/mtccosmicchaos), I built these while learning Blender, so may not be perfect but I hope you enjoy building with them. These were textured in MeshModeller but don't have a lot of visible shadow bugs (as far as I could see).
If you have any ideas/thoughts would love to hear them in the comments :)
