Collision

#1 Create a simple mesh around your shape in milkshape with no material, name it collision and if I recall thats it. If you download the milkshape exporter from here they have some good docs on it and some example files too.

#2 Thanks David, i was naming my collision mesh Col-1, i think that's for Maya though. It works.

#3 Col_1 is maya Col-1 is max i believe

#4 Matt,

After making your shape simply make a collison shape of any CONVEX shape and call it collision-1 in the groups, then hide it. keep in mind that collision shapes have polys too.. so keep it simple.. for simple shapes like small boxes often a 2 sided plane will work (and only 4 polys).

With vehicles, make sure the collision mesh extends past the tires.. of you will have some wierd results.

On a side note.. if you are using Milkshape and want some quick LOD (levels of detail).. just use the "direct-x tool" under the tools option.. drag ro poly count, and save.. regroup as name# with # being pixel size for display.. the smaller the # the farther away it will display.. ie. tombstone2, and tombstone100.. with tombstone2 being simply a plane.. no one is the wiser.
