Is it possible to set up a Toon Ramp Material that would use image textures instead of flat colors?
I usually do a Toon with Ramp checked, interpolation set to Constant, and input set to result to get a hard edge transition with full control over the "shadow" color.
In Maya you can plug image textures into the color slots on a ramp so you can cheat a cel shadow over an image texture by having a "normal" colored image transition to a "shadow" colored image.
Is there a node set-up for this? Is there another way to get this effect?
