vray – RandomColor

0 0 2016/01/25

Just found this great post at the chaosgroup board concerning random colors per object.

Normally i used the vrayUserColor and user attributes to create random hue shifts (more infos here) but this solution sounds even better. need to check it out for myself. as far as i know its only working with the nighly build after the 20th january for now.

 

thats what yolov wrote:

 "Here's a quick example of how it works, along with a scene that I'm attaching:

 - add extra vray attributes to a samplerInfo node (this will expose additional outputs to the samplerInfo)
 - connect the samplerInfo.vrayRndomByID to a ramp's vCoord (if you're using a vRamp) OR uCoord (for a uRamp) | or both, if you intend to switch between ramp modes
 --> the ramp's position and color values will be the range of colors to be distributed to the objects
 --> plug the ramp into a shader and use the same shader on lots of objects"

for more, have a look at the thread.
