sorry, i mixed names
if you make export from origo imd via IMDeditor - export (choice - export imd as obj + triangles), you get file named ala ship.obj + ship.mtl + ship.ref. Look to file .obj and at the end is section "g BND_SPHERES" - these data are, by my opinion, real collision bounary.
1.This section i can not extract from imported ships.
2. How can it be create and integrate into mesh in 3dsmax?
