Using ACES in Natron

Never use OCIODisplay for anything else than viewing: This is not a colorspace conversion node.

In that case, @vkovalcik you need to add an OCIOColorSpace node/set the color management settings in the Write node as Frederic said.

@devernay

The Writers have “Input colorspace” and “File colorspace” parameters and do the conversion internally, which is exactly the same conversion that is done by OCIOColorSpace, so you shouldn’t have to prepend an OCIOColorSpace (). You must set both correctly in the Writer.

That is true but I still prefer to leave those settings to the working color space and add a separate OCIOColorSpace node for better comp readability. Both ways are valid.

@devernay

If you really want to use an OCIOColorSpace node just before the writer, you must set both the “Input colorspace” and “File colorspace” in the Writer to the “Output colorspace” of the OCIOColorSpace node, so that it doesn’t perform any further conversions.

Got it.

This post was made with ACES 1.1 and I haven’t been able to do much work with ACES 1.2 in Natron as of yet and I do not know if there are any (major) changes to the way it works. So when I get the time, I will experiment with ACES 1.2 and write a doc on the new version.
