How to extract vanilla collision mesh

[Radioactivenergy]

any idea how to get vanilla object collision meshes into 3ds max?

The collision data for Fallout meshes is compiled through Elric into binary data. It's not stored in tree node values. So in short you can't recover the collision data in order to re-use or modify it. You have to create it all new unless you have the original 3DS source.
