the Question is in the title also thanks to supernoob and narwhal for helping getting the Vehicle working in game
Do you mean collision traingles? I'll try my best explaining how to place them. To place coltris in the BNEditor you need top first go to the triangles tab. You press add and then choose three nodes ina counter clock wise rotation. If there's a green triangle you've done everything right, if there's a red one you choose the nodes in a clockwise rotation.
ok than you again supernoob but when i do it correctly it just places it in the top part of the notepad panel thing and then the car breaks i show you
In the side bar you have to place the cursor where you want the triangles to be added, then add the triangles. Triangles have to be added into a triangles section in the jbeam file.
