Deformations unsolicited

.

The deformation is controlled by the damage.ini of the mod. You can set there radius, amount of force needed to cause deformation, etc.

I think the first parameter defines how much a vertex from the 3D model can be moved when crashing. It is currently set to one meter, which is too much for carbon fibre monocoques. Reduce for example to 0.20 and no vertex will move on a crash more than 20 cms, no matter how hard the impact is. (Detachable parts will still fly off)
