Is Skatter supported by my render engine?
Skatter's "Render only" feature is currently supported by V-Ray, Thea, Corona, Octane, Indigo, Enscape, Shaderlight, IRender nXt, Twilight Pro, Raylectron and Kerkythea.*
To use Skatter with all the other render engines, you'll need to uncheck "Render only".
If you want your favourite render engine to support Skatter, please go ahead an submit this request to the engine's developers. It has to happen on their side as Skatter has no control over this. Make sure to send them this article.
