Unreal Engine 5.4 - ACES Workflow to Resolve 18

[@tiedtkeio]

Good morning! Happy to have you here. Let me know if you've got any questions about ACES or Color Spaces in Unreal Engine 5! 🙂🙏

[@BrettSimms]

This video was a life saver. Thanks.

[@tiedtkeio]

Haha that's fantastic to hear! Thank you for watching! 🙂

How have I been doing research on ACES in Unreal for literal months now and not finding a solid workflow, until getting to your video and getting it calmly and concisely explained to me within 7 minutes?! Michael, you are incredible! One request for you! I use After Effects (and sometimes Nuke) for Comp work and I wanted to keep all of my Grading and VFX compositing solely in either of these programs. Do you think you could do another tutorial on an Unreal to ACES pipeline for After Effects, and one for Nuke, as well? These programs have different ways of activating the ACES modes, so it would be incredibly helpful to have a step-by-step process broken down like you did for DaVinci, as there is no way I would've figured out this proper method on my own (like I said, months of research!). Thanks again, brother! 🙏 P.S. -- Your v2 of your Anamorphic Lenses for UE are working *wonderfully* at the animation studio I'm working at! I appreciate all you do! 👌

Wow thank you so much! I'm super happy to hear that you're getting use out of my content! And yes, learning ACES can be tricky! I will add your request to my to-do videos! Until then, my suggestion is to really keep track of what color space the image files is on the files you're working with because that step is the easiest to loose track of. If you accidentally leave a render setting on Rec709 for example somewhere in the process and then assume it's still ACES then things can easily get confusing - I've learned this the hard way haha. 😂

After switching, the viewport colour is changed! Is there any way to make the viewport normal, with ACES characteristics, since both the monitor and the material used are in the sRGB colour space?😮

[@StefanoMahfuz]

what is the benefit of doing it through this method as opposed to adding the OCIO file to the color output?

[@tiedtkeio]

Nothing really, you just don't need an OCIO file as ACEScg is built into Unreal by default.

thanks for the videos. very clear and helpful. I'm confused about one thing though. in other videos about UE and ACES we are directed to enable OCIO in the color output render settings after setting up an ACES OCIO file. however in this video you recommend switching to ACES in the actual project settings. ..and at that point there is nothing to set up in the render queue for color output tab at all?! am I right to assume both ways work the same or is there some benefit to switching project settings to ACES?

[@tiedtkeio]

No you only need to setup ACES as configured in this video. Setting up the OCIO file/settings in the render settings (Movie Render Queue) is only useful if you want to directly convert ACEScg/Linear to another color space to work with later. Some people prefer DaVinci Intermediate for example which is close to ACES. But switching in project settings in UE5 enables the output of your EXR files to be in ACEScg/Linear. ☺️

@@tiedtkeio From William Fauchers older ACES tutorials with the OCIO workflow, I have learned that when rendering with ACES you don't want to disable the tone curve. Why is that not the case with this workflow?

[@TheMastercoms]

It looks like your scene changes how it looks in Unreal when moving working color spaces from sRGB to ACES. How do you get the shot to look the same so one can adjust from what they had before? Do we need to do project-wide color conversions?
