NOX Renderer is a rendering software based on unbiased methods. Development is currently in beta stage. This update added control on cautics. So you can make fake caustics - glass materials will work like a fake glass except for first camera intersection (visible one). You can set which roughness value is border value for material to be caustic source. You can turn off bounce from caustic, it will render caustic but will deny any more light propagation from that caustic to scene. All of it is set on Render tab (first one). Also caustics should be redirected to GI buffer, so you can turn it off (Post tab) for the case of scene render difficulty.
Except this were added also pseudorendering engine, another filter - Box2 and fill algorithm choic, which allows to choose sequence for pixel filling. This release also fixes som bugs. NOW is free software, even for commercial purposes.
