So if I understand correctly you already have a walk anim and an attack anim and want to combine those for an attack-walk anim, but the walk anim also moves torso and arms a bit (is that correct?). In that case how about;
1) ent_animate with walk anim.
2) reset the bones of arms and torso etc.
3) ent_animate ANM_ADD attack anim.
yes, but the attack anim has also a legs pose, so I can't just use ANM_ADD as it would broke the legs walking anim. If I modify the anim in med then I could be able to do that, but I would need to do it also for other upper body anims.
