Generative Materials for V-Ray 2 and V-Ray 3

GRay is a Parametric Material Generator for the Rhino Render Plugin V-Ray, with a flexible and easy to use interface for single renderings as well as animation. It gives you the ability to render your generative geometry directly from Grasshopper. Please read the instructions below! Join the Grasshopper board group for support.

The functions of the first version are limited to Standard Materials. Basically this plugin writes vrmat files and loads them to your scene. So beware of using too much materials, this can expand your render time. I recommend to stay under 200 (depending on your hardware), which can be achieved by making Branches of geometry for each material. See the example files for more information. You can find your renderings in a subfolder next to your Grasshopper file.

Optionally, you can use the FFMPEG extension. FFMPEG is a handy video encoder which can be downloaded here (Windows Build 32 or 64 bit):

Just unpack the ZIP next to your saved GH file or copy the ffmpeg.exe to your "C/Windows/System32" folder. This will automatically create a mp4 video and a high quality gif.

Bugs /Limitations

GRay is not really stable and throws exceptions from time to time, so note that I am not responsible for any damage caused by this plugin.

* Currently not compatible with RT-Rendering!
* Limited performance (for the benefit of better compatibility).
* No support for the V-Ray 3 built-in Grasshopper components.
