Do your wheels sink

I don't know if this is a blender problem or mine. it seams that my wheels keep sinking into the terrain when I stop.. I have not had this problem using Max made dts wheels...

has any one else had this problem whit there wheels.

fix for blender would be gate thanks.

Did you make a collision mesh for the wheel, and does the collision mesh completely cover the wheel?

It could also be the values your script is giving to the wheel - all those weight/friction/slip values. Also look to see if making the car lighter changes the "sinking"

I messed with them..... is there some were in script that says how large the wheel readies is?

Sorry about that.. I changed the mass of the car and the wheels don't sink as bad... they still sink when you turn.. mass = 800 sink when stooped 400 stops that... this is sounding more like a TGE than Blender........

The engine creates a cylinder shaped collision object. It knows how big the radius should be from a collision box you create for the wheel just like the collision box for any other DTS.

So when you've made your wheel, create the collision box to be the minimum box that the wheels fits in.

Apart from the that, too heavy a weight value will cause sinkage no matter what collision box you use (of course sinkage is measured against the collision box.

If I remember correctly, the tire object[wheel] does not need a collision mesh constructed for the shape. It is calculated from the bounding box of the geometry, again, me tinks.....I've built wheels with no collision mesh and the wheels still function and cast 'circular/round' shadows....put a 'collison' mesh around the tire, and the shadow becomes square, of course the collision was a box shape I used. I'd start changing the values of the datablocks involved....
