Re: Playing with Sketchup again....
Correct. Kerkythea is a free rendering program. It just has terrible documentation.
Truth to be told, after years of using Sketchup I sort of regret it. While it has a great learning curve, it also uses an entirely different methodology from other 3d software such as Blender. It makes it very hard to "relearn" how to use most other software. From a long term point of view you are better off taking the harder road of learning Blender first.
Baby, you and me were never meant to be, just maybe think of me once in a while...
