I just installed corona 12.2. Has anyone else had issues with LUT files not loading? I get the message "Error loading LUT file C:\Program..... blah blah". Error occurred while reading the file.

Hi,

New default installation folder for Corona is C:/Program Files/Chaos/Corona, "lut" folder should also be here.
Previous lut folder in C:/Program Files/Corona/ should not be there. I assume the missing LUTs are from there? Can you please specify the full path of a missing LUT.
Also have you installed Corona (12.2 and older versions) in default installation folder?

With installation directory change, Corona 12.2 automatically updates all previous installation folder LUT assets to the new path - ".../Chaos/Corona/lut/".

I think i have resolved it by adding its location via the 'Customise/configure project paths' in 3dsmax.

C:Program Files/Chaos/Corona/lut

Seems to be working.

it is a workaround, but all previous LUTs paths should have been automatically converted to the new ones with Corona 12 Update 2.

Anyway, glad to hear the issue is gone.

The LUT still seems to drop out on some files 🤷‍♂️… but I just have to keep my eye on it. Perhaps it will stick on all files I ‘start from scratch’. Updating corona during existing scenes probably wasn’t a smart thing to do
