Tried their almost beta version - and found it quite useless.
They are so obscure…take a look at the renderer comparisons. quite obviously they tweaked the compared renderers’ settings to be the worst you can choose. plus for the gun they show the thumbs correctly and when you click the mr version it links to the pic done by their own renderer. AA is rather nonexistant (lookwise, not technically) and quality is pretty…erm…nevermind

Have you looked at their gallery? Better off using scanline than that &*^%…
