Adding pk3s without models into EOC/KOTF

[527thBattalion]

I recently tried adding neomarz1 Clones Ultima pack into KOTF and EOC and neither worked. I even tried the model type in the menu for Jedi Academy and it didn't work. So I put it into vanilla Jedi Academy and it popped up in the character selection for the teams. Is there a mod for Vanilla Jedi Academy that has an add/load system like KOTF or EOC? And does anyone know how to put these models like the ARCS Remade or Clones Ultima into KOTF or EOC? Thank you guys.
