Mesh

Can someone look at this mesh and see if there is any problems with it? Everything seems to fall through it.

Edit
Is there a limit to the triangle limit? Does the tree entity only do one sub entity?

Only part of the mesh seems to get made into a collison mesh

Edit again
Okay thats alittle weird. It only happens when I preform optimize on the tree collison. but thats less than ideal

When the last parameter is set to zero, the tree compiler will make the collision tree out of the same geometry. This is fast and could be used for testing purposes. However for final versions this parameter should always be set to one. The memory saving can by for 200% to 1200%, and runtime performance gain can be as high as 5 time faster, depending on how much redundancy information is in the original data. The optimizer does not change the topology of the mesh it only extract redundant information.
