Vehicles and simulations

Post by wellander » Sun Feb 28, 2010 6:00 pm

I was doing some R&D on PhysX and found some strange behaviour that you might be able to help me with.
I have a 4-wheel extended and I have a box litterd with debris. To simulate the debris being moved by the vehicle I have made a copy of the wheels, deleted the holes and capped them so that they are cylinders (convex) Now When I add them to the PhysX simulation they get a X-form assigned that result in their size increasing by 100% and they don't effect the rest of the objects in the scene.
Do you have any clue as to why I get the LinkedX-form and the scale change?

Hello Wellander,

Try check the state of the objects before you convert them. Or try uparent the wheels from the rest of the objects. It could be a hierarchy problem if the physx system doesn't support it. The 4whext transforms does include some scaling in it's objects and it might be the physx system might have a problem with it.

Try make a clone of the wheels and make sure they are not parented/linked to another object.
