NOX is a open source application designed to render scenes imported from apps such as 3ds Max, Blender and Cinema4D. The built-in app engine provides highly realistic renders, that you can compare to photo.
Among the main features of the program you will find a materials library, tools for visualization post-production, function to render objects on layers or the ability to generate realistic DOF effect or create blur effect on any objects, even after graphics processing. The renderer engine supports spherical environment mapping. You can set its power and make color correction of texture.
