How do I imports LUTs (.cube and .3dl files) into LumaFusion?

NOTE: LUTs exported from Affinity Photo in .cube format have the red and blue channels reversed. While we normally recommend using .cube files, for Affinity Photo we currently recommend using .3dl files to create LUTs for use in LumaFusion.

The simplest way to import LUTs is to use the Import button found in the Color & Effects editor as shown in the image below.  

• Double-tap on any video/photo clip on the timeline to open it into the Clip Editors
• Tap on the Color & Effects tab at the bottom of the Clip Editor UI
• You'll find the import button just below the library of effect presets

If the LUT you are trying to import is greyed out, this is usually caused by another app registering .cube or .3dl files using a different "uniform identifier" (unfortunately there isn't a clear standard for these file types, so companies choose their own).

In the meantime, the simplest workaround for this is to navigate to the LUT in the Files app, select Share, then share to LumaFusion.
