emotes?

hello i was curious if you could change the emotes (use an Evie emote on Fiona) and if it is possible what .hfs file is it.

Yes it should be possible, given that you can link transformation with emotes
Look at nunya's tutorial on hfs basics

it can be done, but more complicated than described above

the motions are in pc_evy_motion.mdl , pc_fiona_actor_motion.mdl , etc
the sequences emo_jumping, emo_frustration etc are inside those .mdl files

you need to be able to edit .mdl file to edit the motions..
