I have just submitted the Creature 2D Skeletal and Mesh Animation System Plugin to the Marketplace.
The project contains the Creature 2D Skeletal Animation Tool’s plugin for UE4. It has a user controllable Fire Breathing Dragon as an example of how to use the plugin. The dragon character is authored using Creature’s powerful assortment of Procedural Animation Motors. The normal and ambient occlusion maps are generated using Creature’s add-on Sprite Bump Tool. All plugin functions to control, switch and manipulate animation states/information are exposed in the Blueprints system. The dragon character has gameplay logic that runs entirely off Blueprints and the Creature Animation plugin.
Our aim is to make it easy and fun to author high quality 2D Skeletal and Mesh Animations in UE4.
