Material IDs G Buffer

[travistlo]

Im am trying to do a rendering of a kitchen. The Client(an Architect) wants to be able to use photoshop to add differnt colors to the different objects.

I thought vray would save different layers if i apply an ID to the material in the Material Editor. But its not working. (probably my fault) I tried to save as tiffs for each channel, and saved every channel in the g buffer (just to be sure i had the correct one). In the vray Buffer the materialIds look like different shades of green. But when i save that Image, its just black inside of photoshop.

Besides isolating each material i needto change, and rendering an alpha map, does anyone have any ideas to accomplish this?

Thanks,
Travis

Try using the same method and render with Scanline. When you get the images into Photoshop create selections from the Scanline G-Buffers.

well..i was hoping that I would be able to have a RLA file or something already have the materials as different layers, that way i could turn them into selections. What I am doing now is selecting object by material, isolating the objects, render as a tiff with alpha, then using that alpha to create the selections.

How is the Material ID supposed to work?

You can select objects by ID when you save an RLA, but only in a few programs like Combustion, After Effects or the like.

Just enable the G-buffer in vray and also in the rla/rpf and it works.

for photoshop you need "PSD manager" or the "AF Export Channels"

So rerender, basically what you saying is that the RLA file is correct, its just that the PS RLA import doesnt fully support everything?

The AF export Channels is very nice, we need something like this in VRAY!!! Wish I could program.

Thats for the info.

AF export channels works fine with V-Ray, even has a special V-Ray warning if you do not have the proper g-buffers selected.

How do you get a rla into PS?

Does PSDmanager actually work with V-Ray??

Yes, It's been over a year since I tested with it but it did mostly work as I remember, played havok with our render manager stuff though so we had to drop it :P

They have supposedly changed a few things but our programer gets violent whenever I say I am going to install it again to test it, he's softening though

The Photshop CS Cd comes with a plugin for the opening of a bunch of file types, Seem like half of them are 3D program related.
