Oh, jeez.  It won't work at ALL if that's not being passed to dCollideTTL.
The collision code uses that to determine the velocities of the colliding
objects, and thus the best directions for collision.  If those transforms
aren't being passed, then you're going to get some educated guesses, but
mostly garbage, out.
