Hey, thank you everyone!

To answer your question Wil, the next major update will feature a "paintset" of tools. All will function from the main SMEE editor, but offer different features. The tools will include:

-SSE - "Surreal Shader Editor", a .fx file source editor
-A Skin Editor which allows users to preview skins and convert to grayscale bump maps, normal maps, or alpha maps.
-A lighting editor which allows you do rearrange the dynamic lights used in the editor, including their size and brightness

@Nuclear_Winter, they are fully functional now, as long as you have the .fx files. In future versions I will include effects for cel shading, enviromental mapping, and so on

Cheers!
