Viewport “Render” mode
The Render Mode is very well suited for fast visualizations in the design process.
Rendering in “Raytraced” mode
For raytraced render mode: you need a fast graphic card (GPU), ideally Nvidia graphic card with a lot of CUDA.
If you have performance issues try a smaller viewport resolution/size.
Render image-files by “Viewport/capture/capture to file”.

You should work with the realtime view port renderer “Raytrace” (Cycles) for best result if you have a computer with a fast graphic card and ideally support of CUDA rendering (NVIDIA). The basic settings of 1000 samples under “Rhino Options/Cycles/Samples” are much to high. Use 20 samples for working in the viewport and 100 samples for rendering.
Good seetings for raytrace sample quality in Rhino are:
- Low quality: 4 samples
- Draft quality: 20 samples
- Good quality: 100 samples
- High quality: 500 samples

Be aware that Clipping plane doesn´t work for Raytrace rendering!
For difficult interior scenes with very little light you should probably add some artifial light in the room next to the sun/sky light.
An alternative to scene lighting is the setting ambient occlusion which will pronounce the shadows in the corner of the edges and ignore the lighting of the scene.
