I tried making an animated model with a walk cycle and got stuck in the root bone process. It can be cause the original root bone (Or bip01 that is the father of all bones) merges with the pelvis when the model compiles right?
I could get a model to walk to a destination in the beta engine but in the retail the model teleports to its destination even with 1 forward walk animation. It's the older engine yes but it might not have changed as much with the current releases.
Just some interesting discoveries to share here.
