Have you perhaps moved the tri-list geom? The matrix of the trianglelist
should be an identity one. I did this for speed purposes. The best
implementation would have both versions, and determine at runtime which to
use by doing a simple matrix identity check. (Or rather a position and
quaternion check since it is quicker)
