Ok guys... I've almost solved it... The animations on an .m2 file are played one after another... this means that if we edit a custom .m2 model that has two animations in it, and tweak the first animation to start and end at certain frames, and do that for the second animation aswell, then we can assign them to for example "stand" and "run".
The only problem is, when i convert a custom .3ds model to a .m2 it just has 1 animation id: "Stand". I can change it to for example "run", so that it only triggers when the model is running. I can also set the start/end position at any given frame i want.
What i can't do, is add a complete new animation id... Glitchy's MES can edit them in all ways but it cant add another one. So my question is, does anyone of the legendary mmowned users have found a way or a program to add a complete new animation id to a .m2 model. It doesn't matter if it has no data in it, because i can add that later. Just a plain empty new animation id.
Please note that custom npc's means for example play as anime characters, models from other games, etc etc. I've been trying to figure this out since i started to model edit but this is blocking me...
