kuligs2. It put bezierframe>bezierframe.
I dont know if is related but usually when i made a actions in blender , every action is separated, and the keyframes that i put in one are only for that action but for some reason in this mesh they mixed and i had to put keyframes to 0 for avoiding my actions to mix because they mixed.
Edit: i managed to "fix it". I manually muted everything on nla editor. Usually i only need to stash it but for some reasons i had copies in the nla editor that wasnt in my action editor. The bad is that it exported with copies of the animations that shouldnt be there. But i am fine with it. They are only a bit of space more but the meshanimations run well.
