Is there a way with Paint.NET to just take whatever texture you want and turn it into several shades of grey? That would make biome texturing so much easier. If not, are there any ways OTHER than just doing it by hand?
Update: Desaturated the biome textures and this is how it looks now:
Do you guys like it? It looks duller to me, but I suppose that's how desaturation works.
simple black and white usually does that... it averages the colors.... you need a more advanced desaturate filter to make it look good. here are all my toys for paint.net... add the folder to your paint.net install directory. Not all of these plugins work properly... but there are some nice ones. (including an advanced desaturate)
