Re: [Speed-dreams-devel] Does our cars not bend, tilt, prance, swing enhough?

Hello Kristof,

thanks for your feedback, so it seems it is nothing that can be  
improved for SD 2.0 release.

It would be great to see this in SD sson :)

We have definetly to change the collision model from a simple box to  
may a simplified car body mesh or
teh original the car body mesh.

Best regards
Eckhard.
