yes the small curb is a huge problem right now. the project I am working on is not vehicle centered (thank god…I would have changed engines years ago) but it does require vehicles before release… not good ones just vehicles that don’t fly away from the map on the slightest impact. as such implementing vehicles from scratch at this stage it’s a bit over budget. the complex as simple collision cost it’s not a concern in my case… hard to explain why without getting too off topic into how the game is implemented currently. I’ll keep an eye open for other options. Thanks for sharing your insight, will listen to the physics talk you mentioned and maybe get some ideas.
