I started recently to use freestyle and was surprised how much of a difference it can make to your renders once you get the hang of it. Especially de-noised Cycles renders profit from getting some sharpness back in my opinion but you be the judge. I wrote some settings down so I don’t forget them but myself being, well, kind of an infographics enthusiast my notes gradually turned into something that might be useful to others as well. Enjoy.
The most basic freestyle settings and location of the more relevant menus.
Create freestyle lines with multiple colors in a single render.
A way to fake a transparency effect making use of Blender’s collection system.
4) Stroke Styles
An attempt to emulate technical drawing in Blender using freestyle, transparency and procedural materials.
Granted, there’s probably better ways to achieve some of the above and not everything will be super-useful but I hope you’ll find something worthwhile. Any ideas of improvement, you just tell me …
