EPIC Unreal Ed Firepaint Skillz (you mad?)

[nOs*Wildcard]

Very nice Wildcard, however you could do the same with non black and white images. Instead of looking for "white", look for "lightness" of the color. Basically for every pixel RGB, convert to HSL and get the L component and you can do the same with all kinds of images.
Well thought though.

That firepaint limit is native, you won't be able to do much by subclassing textures unless you make your own c++ dll with your custom texture code that is.

Well best I got is this threshold parameter for the program where you can tell it to accept colors of a certain percentage % of white and treat it as white. An extension of the program would be neat would treat varios shades of white as the SPARK heat parameter
