3ds Max Collision Problems

Sup guys, I'm having a bit a of a problem. When I add collision to my tree model and then try to export it it crashes 3dsmax. All the meshes are meshs, not polys. my collision mesh doesnt have any dents or anything either.

Try exporting without the prepended SORT: to your leaf meshes. I know it won't sort the opacity correctly but if it exports successfully then you'll know somethings up with your opacity meshes and not the collision mesh.

Yeah, your right. It is the leaves, but how do i fix it? I tried to deattach each leaf and renamed each leaf, but it still didnt work.

For starters, you're going to want to take out the space in the name of the trunk. Next, you need to add a detail marker to the leaves object. I noticed it doesn't have a 1 at the end.

Im looking at the shape right now, and you can save quite a few polys (especially if you are going to use SORT) by welding the verts the lay in the middle of the edges of the leaves to each corner. You'll be left with the same shape, but with half the polys.

Remember, though, that SORT greatly increases your polycount. If you can get away with not using it, it's usually a smarter option.

Yay!!! Thanks Adam! I added the 1 at the end and now its works :)

Thanks for the tip on the leaves, insted of welding I connected the verts to the center and just removed the verts in the middle so it didnt screw up my texture.

Thanks again :)
