Randomize texture for each object

[yolov]

This is already implemented in the nightlies and will be included in the next SP.

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

Thats really awesome! Gonna try it out.
We've needed a good way to do this for ages. (singleSwitch really isnt optimal, and its a hassle to add more objects).

Would it be possible to get this sampleInfo fix working for shell/elements too in the future?

Thanks once again!

If we add 1 color to the ramp, connect a texture to this color, an connect the vrayRndomByID to the V ramp, obviously, it will pick a random color from the texture, true ?

[yolov]

Yes, but if there's only one color in the ramp, chances are all the random colors will equal this color.
The setup is similar to the one for hair/fur randomByStrand.

Thank you so much for this! This works great. Glad to be able to say goodbye to my old single shading switch workflow

Excellent addition,

I can get rid of my clumsy custom one.

thanks,
