vraymtlid

Anyone know if you can render out a pass with material ID's from vray. I've tried rendering in the default frame buffer, vray frame buffer, all vray mats, and all standard mats. I can't get anything but 0,0,0 black pixels. any help would be appreciated.

can you not just go to the passes and add it and filter through it when it is fully rendered.

The pass renders out completely black in the frame buffer. Using the pixel info feature in the vray frame buffer it doesn't give me anything just the x,y coordinate of the pixel. I expect it to be like mental rays and give each mat a color. Maybe the pixel info only shows up in a post program like after effects or combustion?

 

I'm using 2008 and vray 1.5 sp1, not sure if that makes a difference either.

i'm not sure if I understand?

 

vr mtls id

 

save it from the drop down (as a whatever format) in the vray frame buffer

uggg....sorry. I R NOOB. I didn't realize you had to assign the material ID in the material editor. Thought it was derived automatically somehow. Thanks for the help.

i am having exactly the same problem that my vraymtlid renders entirely black. how were you able to assign IDs in the material editor? i cannot seem to find any possiblitiy to assign IDs to any materials.

 

thanks for any help!

 

edit: found it!

There's a handy script included in the soulburn collection which will randomly assign material ID's for you:
