Hello FeralHeart!
If you are just getting into making presets or you haven't made them in a long time and you're just looking to remember how to make a preset, I have made a tutorial for you! These videos will teach you the basics of making a preset! More videos will be added to this list as I make them!
Here are the first 4 videos which will teach you how to make a basic one-sided preset!
SpicyDirt's Preset School: Getting Started
SpicyDirt's Preset School: Body Basics
SpicyDirt's Preset School: Head Basics
SpicyDirt's Preset School: Tail, Eyes, and Mane
I do apologize for the mixup with the mane fix in the last video, but the true fix is in there!
I hope this helps people out!
