I've tried many different commands/scripts to get my player and AI to lean and doesn't work.

Scripts/Commands tried:

S1 playmove "InBaseMoves_Lean1"; S1 disableAI "ANIM"

this switchMove "InBaseMoves_Lean1"; this disableAI "ANIM";

I've tried it on several triggers and move commands. It's not just this specific animation either. 90% of these animations from the Animation Editor don't work.

On another note addon AiA animations don't work either (ported animations from ArmA 2).
