I am running DaVinci 10 and have several extra LUTS (dat & cube) installed on my system.
Weirdly, some display a result when applying, and some just don't seem to work when I activate them.
Any idea what could be the reason for this?
It is possible that other LUT generation apps use the .dat or .cube file extension but the format within the file is not recognised by Resolve. Open the .cube that does not work with text edit and compare the structure to one that does.
