The only option that comes to mind is to do a second rendering with the material painted very vivid unique colors. Using no lighting with make the rendering appear uniform in color and that might work, but this would be a very crude way of doing a materialID channel.
Thanks for this. Very straight forward! Only question I have is can V-ray for rhino output a file with composite Object / Material ID's? I take your point regards the colour contrasts needed for selection and high resolution. The issue comes when there is much layering of information in an image, say of a view from outside to inside a house. You can have alot of layering of information and thus a much more detailed breakup of a material / objects that are visibible. It CAN become hard to isolate using colur selction when in photoshop, due to the relative small size of the individual pixeled areas. In C4D they offered a photoshop layered output file with individual layers pertaining to the inividual Object ID's / Material ID's. Does V-ray for rhino offer something similar?
Thankyou for the post, I understand that as the material ID only exist in the new Vray for Rhino 1.5, however i am currently using the vray prior to the latest version...is there any other way to achieve similar effect? Thanks David
Thanks Christopher. my question here is I can't find Material ID image, even though I've chosen Material ID channel. (I can find render ID image though)
Qi Shen In your materials menu you have to set the ID color. Right now all the ideas are most likely black so you cannot see the difference. Set each material to a different ID color and the rendering VFB channel will show it. Hope that helps.
Hi, I am looking for the drop down menu to save my VFB channels and I can only see Alpha and RGB options although I am using 1.5 and rhino 5? Thanks in advance Neil

Thank you very much for all of the informative videos! They are very helpful.
Make sure you have enabled the new vfb channels under vray options-->VFB before you render, then you should find the channels in the drop down menu.
This is what I was looking for. Thank you!
