for a map im makin, ive created some "Carwrecks" from the DAE files of some vehicles... i first tried "j-beamed" ones with physics but they didnt behave quite right... then i just used the meshes, but nomatter what i did or how i set the "collision types", i couldnt get any collisions to happen. Now... heres something cheap i came up with: so...? can i get away with it ?
There is a guide on how to get collision to work on complex meshes. Since you can't use the visible model as collision mesh (too many polies, will end up lagging the game), you should use a lowerpoly model. If you use Blender, I made a video tutorial time ago: Or for Sketchup, Sam made one too:
