10/10 you are making brilliant cars!I'm also making bms and audis from blueprints but they are not so good as yours !I really want to learn how to make so detailed cars in algodoo!
P.S Please tell me how did you make the lights and signals?
Select everything and click on "no self collision". Also add 3 hinges on each part. I noticed that you have fixed them with around 1-2 hinges and some parts don't have hinges at all. Hope I helped
On the scene you have uploaded there aren't 3 hinges per part. If the same happens idk. Try making breakable cars as I do them. My strategy isn't brilliant but with a few tweaks you can make a great car on that way
