... I don't see how... Unless DB object collision switches on polygon collision by default... I thought the command used two spheres to test against collision with, in which case that wouldn't be polygonal. You're saying you could have 1 .x model of a house with an open door, and another .x model of a little kid, and the little kid would collide with the model and stop, yet still be able to go inside the house, just using the built-in object collision commands.
If you're justusing spheres and boxes as your .x models then yes it'll work
