Skinning Editor

The Skinning Editor is a module which is added to the Sprite Editor after installing the 2D Animation package. Use the editor's tools to create the bones of your actor's skeleton, generate and edit its mesh geometry, and adjust the weights that bind the bones to the meshes as you rig your actor.


The Skinning Editor is found in the modules drop-down menu at the top left of the Sprite Editor.
