Flamingo is no longer available to buy or evaluate.
Fear not, because Flamingo is not gone but it has been replaced by the new advanced renderer built into Rhino 7.

Rhino 7 includes many modern advances such as:

•  Physically Based Render (PBR) 
• Materials Rendering denoisers for fast results 
• Advanced lighting 
• Realtime in viewport working mode 
• Plants and shrubs are supported by purchase of LandsDesign for Rhino plug-in

Check out our latest Novedge Webinar featuring Lands Design. Lands Designis an advanced solution for landscape design and a great asset for Rhino, AutoCAD and Civil 3D users.

You will be able to duplicate essentially every aspect of Flamingo with Rhino 7 built-in tools and plugins.
