OK, so… im not yet good with collsions…
How can i set some faces to act as collision objects, not visible geometry? Do they need to be a separate filefrom the actual model?
If your using Pandas physics then you can just have them in the same file - just export multiple objects, some for collision, some for visualisation, and tag the collision once to be for collision - the Chicken manual documents how to do this. However, if using ODE then a separate file is probably easiest, and do not tag the collision geometry as being for collisions - the ode method to turn geometry into ode collision geometry can’t handle panda collision geometry, only Panda visible geometry. Strange I know, but there it is.
