Importing collision into blitz

Want to ask something here.

I imported my models into xworld 3d, and used the collision the program supplied.

The problem is when I export the scene as a b3d format, there is no collision at all when I import the file into blitz.

Anyone knows how to import the collision into blitz?

Nope. I don't think you can, but Blitz has a collision system. Check it out.
