Like in Final Fantasy Open rpg, i tried to attach an animation to both hand of a unit. What i did is I create two action triggers, one is with the hand,right origin and two is with the hand,left origin. The problem is the animation is only attached to one hand... can someone help me to attach the animation in both hands...
You could use an ability to attach the effect instead of special effect actions, which might be better for your needs.
Make a dummy unit with target art (or caster art, as appropriate) set to your two attachments. Give it to your unit when he does whatever. Remove it when he does something else.
