Change the position of a part of the model? Uh, only by moving the skeleton around at the moment. If something similar to the Field Sprite's HRC files is decoded, then you should be able to fiddle with the actual skeleton....but I don't think that's possible at the moment.
In theory, you *could* try importing the .p files for the model you want to use into a seperate LGP, write up a HRC for it, and fiddle with it in Ifalna...except battle scale models won't fit in Ifalna's zoom range. And Scaling down battle files using Ultima is more effort than it's worth, at the moment, really. :\ I guess I'll just have to wait, and continue sacrificing fatted Porn Spam to the FF7 hax0r gods... :weep:
