Hi, i am using transparent toon material with outlines. And i got this terrible overlapping zones. How can i get rid of em, so there is only outlines left?
Try to increase the Ray Bounces value in the Lighting tab or just try to avoid overlapping. Render engines don't like that, especially with transparency. ;)
P.S.: Actually overlapping is not the issue, it is caused mostly by surfaces laying on each other. As in real life there should be a little gap in between. Unfortunately modeling software don't consider this real life fact.
