Pre-defined objects seen in the code such as `slider[0]` and `layer[0]` are exclusive to the Adobe After Effects plug-in PixelsWorld.

Download the game's internal LUT file here. Take note that this is not a traditional LUT - it's hard to explain but you can't use it as if it was any other LUT for filmography.
In your Adobe After Effects project, apply the PixelsWorld effect onto the layer you want to apply ZenlessLUT to.
Set the Language parameter in PixelsWorld to GLSL and click on Edit. With ZenlessLUT.glsl open in a separate text editor, copy-paste the code onto the World formula editor. Once done, head onto the first Layer parameter and set it to the imported LUT. Control the strength of the LUT with the first Slider parameter. Be sure to set the Mipmap filter parameter of the effect to None.
If you have issues with flickering visuals/crashing, try turning off Multi-Frame Rendering in Edit -> Preferences -> Memory & Performance.
