blackfoot, a visible bone_pelvis glitch with certain bf2 models used in bf1.
kit fisto is victim of this blackfoot and we must find a way to fix it

Known blackfoot models:
Kit Fisto
Quinlan Vos
Qui-Gon Jinn
Cin Drallig

Does anyone know how to fix these models with either a hex edit or through XSI?
If anyone has a way to fix I will upload the blackfooted models.

I'd imagine youd have to edit the skeleton in XSI but I wouldn't know how to do that

If you can contact the person who made the model you can ask him to hide the bone_pelvis. or you can find the model and reimport it into xsi and then export with hidden bonepelivs or you could try to hexedit somehow
