Hi! i have this problem: ...the biggest one is that collide model has WALL objects only with one face for surface definition. That's a mistake, as when you crash from the backface side, car stuck on collide object and there's no way to come back to road.... how can I solve that?
What software are you using to create the track? you need to create a copy of this wall, flip the object faces and them merge with the original object.
Blender would be able to do that. Select the faces, Shift-D to duplicate them then right-click to cancel moving them, then then choose Mesh > Normals > Flip Normals. Hope this helps
correct me anybody if i am wrong, but thats not a good idea, double sided walls will get you stuck on the lightest touch, you would have to move the wall at least a "brick" (0.1m) wide away from the other side of the wall
@fughettaboutit Yes I did wonder about that myself. I've always made my 'wall' objects have some depth to them and that always works fine. But my experience is limited so I was more just answering the question about how to implement @Johnr777 's suggestion. Sorry if I've misled. Lol
