Light Pass Mantra [ EXR AOV ]

[Ultraman]

Hey Guy -

there is any way to load all light into IFD then just a few Light effects on the Image and the rest of them be in the AOV Pass ?

im not sure my question is correct ;(  

i have 2 main lights just wanna effect on my Final image in Exr file and ther then be Auxiliary or like Attribut but actually  is real Light . 

i Don't wanna make two Mantra Node , to do Dirty Way

hope my explanation be clear what I'm saying

Thanks in advance.

If the question is can you have an AOV containing lighting info that is not in the RGB then I think yes. However in your shader you would need to set what amounts to another shader tree to then feed your bind AOV (which probably will take twice as long to render) if you really want to keep it out of the beauty RGB. So either you dirty your renders or you dirty your shader.

If you're rendering each light to aovs anyway, you can just subtract the light from the rgb after rendering
