Thank you so much for explaining how you do your lines!!! the color "fading" (which probably wasnt the best word), I was talking about was specifically how you got really vibrant outlines that change color depending on what part of the texture its over!! Ive only really ever seen models with one color outline, but theres quite a few shown here!
(first ask) ohhh! So, since the original mesh has been duplicated for outlines, the outline mesh can either share the same textures as the base mesh or use a new one. For this model I made a separate texture! (I think with this model in particular, pegasuskiss's character design and colors also really helped sell it!)
But when I made this ranch model, I mixed the base texture with another color on multiply mode
