I am having some serious issues with aces colourspaces that i did not previously have with the 1.2 setups.
THere is a discrepancy between vieuwport rendering and rendering them out directly (all are png) same problem with exr -> png
I`ve run more tests with the default ocio config aswell. There is also a difference between the viewport render although with the default config its more negligable. and it might just be becouse of the resolution that it appears brighter.
