I discovered that Photoshop has a bunch of LUT tables built in and wanted to use them in my UE4 scenes, so I went about exporting them all out, and I thought I would share the fruits of my labor with everybody.

The second is the raw .png files. Please note that when you import these yourself, be sure to set the Texture Group to “Color Lookup Tables” in the texture options.
