Hi.. I am following the exact steps and tried exporting in exr. When I composite them in either nuke or photoshop, my image gets too over exposed as compared to the desired output. I even see small pixilation due to that over exposure. The colour is not the same. I have tried everything I could think off. Do not know what the problem is.. Can you help me out..?? Especially the linear dodge blending mode rips the whole image apart but the same thing done by you and other artist tutorials, they get awesome results but that is not the case with me.. I am just using diffuse and specular direct and indirect to learn for now..
I even followed your document related to this issue and have checked all my preferences n all. They are all good.
Help me please.. I have attached 3 images to explain the issue. One image is showing all the default settings I have used in Maya while rendering..
Regards
Aayush Aggarwal

To have them look the same, you need to view them through the same OCIO display transform in Maya and Nuke (Photoshop does not support OCIO). In Maya OCIO is set by default to an ACES config. Nuke is not set to use the "Nuke default" OCIO by default, so you need to manually set it to ACES to match the two. I'd suggest using the same config file in both programs.
Thank you for the solution.. I did not change anything in Maya and left it as it is with its default settings but I did change the viewer colour setting to OCIO and ACES 1.1 in Nuke as you told. This worked properly and I got the same result as My Original Beauty Render.
But this is so weird because when when I follow Multi Pass Compositing Tutorials in Nuke, upon looking closely I found no one changing their Colour settings in Nuke or Maya or After Effects i.e. I noticed that they all kept everything as default in Maya and Nuke and AE. Thus, they are getting awesome results but for me this does not work. Can you tell me why is that happening.? Or am I missing something that these tutorials are not showing??
Is SRGB gamma different than ACES 1.0 (SRGB) ?? May be that is the reason behind all this??
"Is SRGB gamma different than ACES 1.0 (SRGB)"
Yes, it is completely different.
The tutorial is from 2020 and both Maya and Nuke are not using an ACES config, rather both are using the same older sRGB linear workflow. That's why they match.
