Order of VRAY Elements in Photoshop

[kenc]

I've been trying to layer VRAY rendered elements in Photoshop, but haven't been able to get it to look like the fully rendered JPG version. I'm using Diffusefilter, raw GI and raw Lighting. Can anyone help out.

Thanks in advance

Thank you so much Morbid Angel for your reply. Your info is greatly appreciated.

Looking at your graphic layout, which blending mode is 'ADD', 'SUBTRACT', etc. Some of the names for the modes are misleading or I don't understand what they mean, 'LINEAR DODGE', "SCREEN", etc. I am not a photoshop expert but I do know how to use it for my everyday needs.

I'd like to explain further what I am trying to do. I have several architechural scenes that I am rendering to vray elements. The lighting, etc has been setup for a library of materials. What I am really doing is applying 128 grey to all objects and rendering elements for objects like floor, walls, ceiling, etc. I then layer the elements in photoshop (raw lighting, rawGI, etc.) with the different blending modes. The diffuse color does not come the rendered vray element but rather a color is choice in photoshop. I open say the diffuse element(128 grey version), using its alpha fill it with a color of my choosing and this will be my diffuse color. I then use this diffuse color to multiply with rawGI and raw Lighting, etc.

I hope I have been explain so that you understand.

yeah i see, you dont really need to do that. If you render with render id pass, or material id pass, you can use those colors to isolate the specific objects. This should be easier.

or use the multimatte element, and you get three mattes in one time.

Unfortunaetly the rendering and photoshop action has to be automated so I can not have any human interaction. Therefore I need to render the different object seperately using vray matte object and alpha contribution vray properties. I haven't had a chance to try out the layering setup as yet but will give it a try today. Thanks for all the help and I will reply back how it went.

One question about your layering list

Group - Add
--VRayRawGlobalIllumination - Multiply
--VRayDiffuseFilter* - Normal
VRayRawLighting - Multiply
VRayDiffuseFilter* - Normal


Layer1(Bottom)

Diffusefilter-Normal

Layer2

rawLighting-Multiply

Layer3

Group 'rawGI*Diffusefilter'-Add(Linear Dodge)'

Diffusefilter-Normal
rawGI-Multiply

Is this correct?
