Raycast Multipass Question

Recommended Posts

Hey guys,


I come from Softimage background. I want to set up passes where a specified objects primary rays are ommited from a render, but it still provides secondary rays to what is being rendered. 
Is this possible? Any help would be invaluable.

Thanks,

Morgn.

RE: I want to set up passes where a specified objects primary rays are ommited from a render, but it still provides secondary rays to what is being rendered. 
Not sure if I understand. My assumption is that the "primary rays" mean camera rays and "secondary rays" are GI, AO, Reflection etc. 
In that case, just add a "Compositing Tag" and untick "Seen by Camera". 

If you are using a third party rendering plug-in, that will require other steps.

@Morgan Powell Are you using After Effects to composite?

 

I believe you should be able to output the following passes, then combine them in AE or Photoshop using the Add blending mode to give you a result representing all but the primary rays:

 

Indirect Diffuse, Indirect Specular, Refraction, Material Luminance

 

Let me know how this works out for you!
