When I insert Stick tool for the biceps and the forearm, the pin point in the scene is very, very tiny, deforming just few pixels, and doesn´t bend the arm neither. It's very weird because with other psd file it is working perfectly and I've followed the same steps.
Thanks in advanced!
I solved the problem by myself. I missed to put "+" in the Character Group in Photoshop. Yuhuuuuuu!
Ha yeah. Basically it's weird, but you have to make the whole puppet "independent" for him to move like that. Glad you figured it out.
