Okay, I've made a head animation (see attachement). The problem is now to implement it into the game. Just putting the file name into the "ANI file" line in FRED doesn't seem to work. I also can't find a .tbl that seems to be used for this...
Well, funnily enough I very recently had serious problems figuring out how to get my custom head anims to work, so I added what I learned to the wiki just the other day. The biggest obstacle was realizing
this, so you probably need to copy your file to create those variations and then refer to it in FRED the same way as they're referred to in that table. You might also want to make sure that the
colour palettes are right. I hope that's of some help, since I myself spent quite a few frustrating hours trying to figure all that stuff out.
I don't think you need to add anything to any table in order to be able to use the anims in FREDding.
