I would like some different textures for the glass breaking in the cars... If that's possible. And I sometimes tear the front windshield and I looks weird (I already mentioned this is asking if the mesh tearing should break after certain tension).
You can modify \vehicles\common\glass_dmg_s.dds for a different appearance. Beam based physics is lacklustre when it comes to ripping and tearing. As a consequence, the vehicle artist is left to choose between the windscreen deforming weirdly in a crash, or large chunks of it disappearing altogether. The former is probably preferred over the latter.
