Hi,
there are two versions of the software - RenderGin and RenderGin Pro. The Pro version includes the direct NURBS ray tracing, 3dm, IGES and step import. During the beta period you get RenderGin for 50% off. That means for the european market RenderGin is available for around 400 Euro, and RenderGin Pro for 2.250 Euro. We just can give the recommended retail price. For the US-market please contact our reseller Models from Mars: http://www.modelsfrommars.com/MFM/RENDERGIN.html
