You need to go into the game, then at the main screen go to Tools, and then Preset Maker. Go to your preset and select it. Then click export.
Your preset is now located in C:\FeralHeart\media\presets
and it is titled with your username and then the number of the preset it is.
Upload this .fhp file to an uploading site, give your friends the link, and have them download it and place it into their own presets folder. (remember, presets. not my_presets.)
This will give them the ability to see you use the preset ingame, but not use it themselves.
