I tried changing the dragon model into the myloc model some time ago (planning to make a semi-trailer, semi-short film for istaria, need to be able to run around as myloc queen for it ) but so far I have no succes, my steps:
1.change the dragon skeleton file into the myloc one.
2.change dragona_u.ent into myloc queen.

then i logged and all the ancient on my screen were invisible, size did go right though, and no dragon emotes so it did load the right entity file (or wrong depending on you view LOL)

3.then I decided to change the dragon texture file with the myloc one (im guessing [dragon_u_wings_head_base.sha] is base texture for dragons)

but still nothing, so now I come here asking if it is even possible to change the models to such an extend. and for help if it IS possible
