Currently I'm playing around with the material system of Gnoblins. Many models in Gnoblins are recoloured dynamically to have the option to quickly add new colour variances. I wanted to add material which looks more like metal which isn't easy when working with handpainted textures only. I've come up with a system displayed in here:


As you can see, there are several materials displayed. For one I just recoloured the skin and clothes, or make the gnoblin look like gold or silver and play around with other effects.
