I Combined Beauty and Light Passes in Nuke and Got AMAZING Results!

[@vijayctamil]

I usually render Beauty pass split by light aovs , and rebuild them for full control. For simpler render passes , all those control is unnecessary and expensive. But the divide to get the changes and multiply to add it back is just intuitive and great. I just feel stupid to not realize this basic math. Helpfull one mate.!!

Glad this was helpful!

Thanks for the tutorials Shahid, I'm really liking the stuff you share. Just wanted to clear something up as I triede recreating this cool concept and i noticed some sort of initial weird results. It seems to me when making the beauty rebuild using the shader AOV's then dividing it by the original render and then multiplying it with the light pass rebuild the changes I did with grade nodes in the shader AOV rebuild is the inverse of what was expected when mixed with the light passes. Fx gaining up and gamma down resulted in less contrast when it should create more contrast, while tint shifts in the diffuse color or transmission indirect was also inverted. A 'fix' was (i'm not sure if i'm totaly wrong, if i am please let me know lol) to check the reverse option in the grade nodes which then in conjunction with the divide by render and multiplying with the light passes gave the expected results. However this could yield strange results i expect when doing more advanced shader AOV manipulation - I'm curious to hear your openion if i'm totaly off the reservation here. Thanks again :D

when you do divide with original beauty layer make sure to to connect properly i mean in the merge make sure to connect B pipe to original beauty and A pipe to shader rebuild then do divide operation fi the B and A pipe switch then you will see inverted change when doing manipulation on passes, just check once,

Please make a video on geometry projection in nuke like projecting surface textures

Nice one!!!

[@VFXSHOWDOWN]

thanks, as we discussed the divide and multiply using merge node, we can also do this operation using expression node

Can use this same method for arnold render also right?

[@VFXSHOWDOWN]

Yes, the divide and multiply you can use this for any render engine passes to combine light and beauty
