I've tried to set up ACES multiple times using the linked method, and it never works.

Hi everyone. I'm on C4D 2025.2, and Octane 1.5.1.1, and I am having no luck getting ACES to work correctly. I am using the following guide: https://help.otoy.com/hc/en-us/articles/12818430938651-Octane-ACES-OCIO-User-Guide-for-Cinema-4D

I have followed this guide to the letter, multiple times, and it never ever results in the live viewer showing the same image as the picture viewer when rendering. Also, my renders suddenly jump from 50 minutes to 17 hours. Is that normal???

Whenever I go to test render, I'm using embedded/raw, and the colours in the render are completely blown out. I've tried this probably ten times and it's the same result every time. The Live viewer image looks fine

Perfect example is here.

On the section in project settings, it asks you to select the location of the ocio.config file, and then once selected, to set the render spaces to ACES2065-1. The problem is, that's only selectable BEFORE you enter the config location. Once you enter the config location, the option to select it disappears, and it defaults to ACESsg "New Render space: (sRGB linear workflow")
I'd really appreciate some help with this, because it feels like something is missing from the guide that doesn't account for changes made in 2025

The guide does need an update, as many changes in Cinema 4D have occured since it was last released. For most users, if you need ACES output, it is simplest to enable the ACES Tonemapping option in Octane Camera > Imager > ACES Tone Mapping. No other settings are necessary, as Octane will automatically tonemap the image to conform to ACES output via standard sRGB.
