Color Mask

Hi! Everyone

I am new in V-Ray. I used to render with Brazil.
In Brazil, I had an option to mask the material in Black and the background in white (an example is enclosed) so I could in Photoshop select the material and isolate the background and edit the material easily.
Is there such an option in V-Ray?

Thanks
Meir

Hi @StarUpJewelry

There are numerous ways to achieve that in V-Ray for Rhino through our Render Elements;

If you want to mask specific materials, you can use Material ID Number or Material ID Color, which will create a mask based on the material ID Number or ID Color parameters. To have a further read, please check:

You can also use MultiMatte Material which will create red, green, and blue selection masks based on the material’s ID number:

Thank you! Nikoleta
I try. it’s easier for me to give the material plaster black and the background white and render with Rhino renderer

@StarUpJewelry Did you try Material Random Color? So you should get masks without additional steps - every material get a random mask color for easy selection in postwork.

I got it
Excellent
It’s better than in Brazil. Easy to switch between RGB and the color mask
Thank you!!!
