With Corona 8, I get an error message every time I open my scenes. It says that Corona couldn’t load my custom LUT. No matter how many times I reload the LUT and save the changes, the error will show up when I open the scene again.
This never happened in previous version.
Was the LUT file previously in the same location? It seems that the file is in a very long path and this can cause issues generally in Windows, not only in Max/Corona. Can you try moving it to another folder (maybe just C:) and see if it’s the same?
That was my first thought, and I may be very wrong, so if it’s not a path length issue, we will need to look into this further.
Loading the LUT from the desktop seems to fix the problem.
It’s pretty odd since I never experienced any problem loading the same LUT from the other location on Corona 7 or other version. Something changed.
I have saved the LUTs on desktop and still having the same error.
Can you please delete the Corona folder (or backup, remove it from the root folder temporarily) from your ENU location: C:\Users<Username>\AppData\Local\Autodesk\3dsMax\20** - 64bit\ENU\en-US\plugcfg\corona, and see if the issue persists?
Didn’t solve my problem with LUTs
Error loading LUT file ‘C:\Users\Admin\Desktop\LUTs\LUT4.cube’:
LUT file does not have standard format. Learn more »
Still getting this error with every .cube LUT
Attached the screenshot of LUT4 properties and the LUT requested.
What i’ve noticed is that when the error appears for the first time with a LUT then it appears also to all the other cube LUTs.
Sometimes instead with same cube LUT doesn’t give any error.
When error occurs i delete the LUT property from tone mapper and then the problem disappears for a while, then randomly occurs again.
Very weird. i have tried also with max 2019…same behavior.
Thanks

This is not working for me either.
Every time I open a scene I have to re-load the same LUT for each camera! That’s very frustrating.
Is it possible the share the scene with just the cameras and the LUT that’s being used?

Thank you, can you please clarify if the Asset tracking path (Shift + T) in 3dsMax is correct path for the LUT location?
If you delete the LUT tone mapping operator and add a new one using the + button do you get the same issue when loading a new LUT?
Regarding the Asset tracker, I can’t open it for some reason. It has happened before and I have managed to fix it just by re-installing Max. But that’s something I can’t afford right now.
This could be the main cause to your issue, autodesk suggests the following: https://knowledge.autodesk.com/support/3ds-max/troubleshooting/caas/sfdcarticles/sfdcarticles/Asset-Tracking-missing-or-will-not-open-in-3ds-Max.html
As always do keep a backup of any local files.
Can you also send through the LUT files?
Thanks,
Rowan
I also get this error message every time I open a corona 8 Scene in 3DS Max 2022.
In the LUT drop down layer is says ‘empty’
I then delete the layer and add a new LUT layer and they all appear again.
Its a little frustrating and worrying, as I have an animation to render and worry that nodes will have the same issue.
