Right now, rim lighting on the Toon Standard shader seems to be purely additive. White is bright, black doesn’t render. I propose a drop down that allows us to select what blend mode we’d like for the outline. Two blend modes that would be incredibly useful would be of course multiplicative blending for darker rim lights, but also overlay blending so that we can accentuate and amplify the existing albedo textures by using a color close to white. This kind of behavior would be in line with other toon shaders that have an ‘albedo tint’ slider for their rim light coloration.
