Description
I've noticed a strange bug in TRAA when testing static scenes. Turns out the initial value of
previousModelWorldMatrixinVelocityNodeis incorrect. When there is no motion in the scene, the velocity should be 0. Before this PR, motion was computed since the previous and current world matrix values didn't match.
