When importing and exporting colour transofrms and LUTs you can use the location shortcut button at the lower left of file browsers to switch between the standard file locations.
You can use files located anywhere on your file system, but it is recommended you store your custom LUTs and colour transforms in either the Project or Shared location.
As of the 2017.1 release, the Autodesk Transform Collection is a superset of all previous releases. So it is no longer necessary to keep previous transform collections installed on a workstation in order to load archives created in previous releases.
Legacy Discreet 1D LUT files should have the .lut extension should be stored in the Project (/opt/Autodesk/project/<project name>/lut) location.
Legacy Discreet 3D LUT files have the .3dl extension.
The 3D LUTs installed with Flame are in the Lustre Colour (/opt/Autodesk/Lustre_Color/lut/Lustre_Color_3DLUTs) location. Use the Project (/opt/Autodesk/project/<project name>/lut) location to store 3D LUTs specific to a particular project.
The Colour Policy files for a project are stored in the Policy home folder:
