Hi guys, Trying to get into Animation Box. When I open a template with ready characters I can like drag and drop on the pre created body parts such as heads, arms etc. But when I try to drag and drop another PNG object into the scene I see the +add icon in screen but it doesn't add anything. Especially I created a new project with only skeletons at top like human holding a gun etc and I can not drop any images into work area be it from the folder outside of Animationbox or from the left side ready made images. Thanks
