What is this for?

This editor is for Emissive Skin Resource Pack for Bedrock Edition (created by me, Pintacred).

How to Use:

Movement: Left-click to rotate around the model. Right click to pan around it. Scroll to zoom.
After you're done editing, download the mcpack and apply it to Bedrock Edition and select what arm type to use.

Sadly it is not compatible with other resource packs that also use the player entity file.
