So are presets hard i'm just asking cause I tried making one and I like.....How you say,FAILED....So i was just wondering how easy is it?
Heheh you must meet the basic requirements first before trying to make one. You'll need a more professional art program like GIMP or even better, the expensive Photoshop. At first it may seem really complicated, but as you gain more experience with the program and file finding, then you'll be able to make great presets in less than a few hours.
If you think that a few hours is long, then you might not finish your first full preset until the next day (if you want it to look pretty darn detailed). Once you get the hang of it, then you might even get into preset-volunteering! People will start to want your presets.
So I cannot answer your question entirely because the difficulty of making presets varies upon the person making the preset.
