Override exclude

[glorybound]

Wouldn't the color for excluded elements make more sense being white? In PhotoShop, using the multiplier mode, they would be ignored.

Linear comping is generally done additively so black will disappear, multiply can cause a lot of issues!

good to know, thanks

[glorybound]

can you elaborate. In Photoshop, what would this look like?

The issues? Mainly along edges where you've anti aliased objects - you can get some darkening of objects so they look a bit "halo'd".

[glorybound]

but, how are you recommending that it is done, if not multiplier in photoshop?

Linear Dodge (Add)

Linear Dodge (Add) for true 32 bit comps
Screen for fake 16/8 bit comps. You will not be able to match 100% to beauty /32 bit comp using 8/16 bit but then if you comp then it means you will retouch it so it should not matter.

Well, it's not working for me. How about a step-by-step? usually, I copy my AO on my main and set it to Multiply; dropping the opacity to around 40%

AO is not part of passes. Is an extra "Effect". There fore you can use multiply on it. There is nothing physically accurate about it that reflect real world.

Okay, that takes me back to my original post

Uh so you mean " Override exclude " in AO material? Because I was not sure what is it related to

I guess it might be cool to just have swatch that we can pick for the color of excluded objects.

What about reversing AO colors: Occluded = white; Unoccluded = black.
This will give you a negative-AO information, then you have to just revert the information again in photoshop and use it as you normally do.
The difference would be that the excluded object will now be in white color which is exactly what you want.
