Painter? SWEET!!!
Curious, is it possible to make the painter do textures as well?
Make a "wood" house, that is actually a concrete house with a wood texture painted over.
This would be useful to make structures that would not burn down easily and would be durable.As far has how to put this in the actual game however, I am not sure. Solid colors are easy as you can use dyes. This texture idea (if it is possible) would be a bit harder.
The texture idea could be well possible. I could add a tool which will refer to the next block in your actionbar, and apply the texture of it to the "paintable block" you clicked.
However, a big issue would be MCForges Texture override... a block can only grap textures from one file... you couldnt mix up vanilly and IC sprites, thus i would probably have to pick one.
