I'm making a custom script for work and I've hit a roadblock. I'm attempting to add a simple Tint effect to a layer but can't seem to find out how to get that done. I noticed that for the basic Effects and Presets there are .aex files, but no .ffx files (that I can find). So when trying to call the .aex file using applyPreset I get some errors. This is my code currently.
