UGC stands for User Generated Content. Basically, it's anything that a player can upload into the game for other players to see.
If you already have a completed template, you can choose the template from images below the new button. These images
shown will be jpg images in your custom folder (example: C:\Nexon\Library\maplestory2\appdata\Custom\Equip). You can
open your folder containing all the images by clicking on the open folder button:
You can also move jpg images to this folder and they will appear in the Maple Workshop after you close and open it back up.
You can also create a new template. If you do, it should create a new file and open up a default image editor (Paint for example).
You can from there copy the image and paste it onto a better image editing software, such as Paint.NET, Paint Tool SAI,
or Photoshop. I personally use Paint.NET. You can of course use regular Paint, but it will be extremely difficult because
there is no layer functionality in such a basic image editor.
Make sure that if you are copying and pasting the template onto another image editing software that you save it into the folder that contains the images.
Once you have saved it into your folder or replaced the original template, any changes that you make to this image will
immediately show up in the preview in the Maple Workshop. For example, if my character was previewing template_1535290684.jpg,
I can change the template from this:
and saving it will change my character preview from this:
This automatic update of the preview is extremely helpful because you will make many changes to the template and
will want to see if your edits line up, since two opposite sides of the template will wrap around.
For general tips on the actual designing of the UGC, I don’t really have much to offer personally, since I am not an artist,
nor do I have a tablet. It’s probably a good idea to use reference pictures of actual clothing online, or if you’re basing
your character off of some anime character (like me) or character from a movie, you can design your clothes off of them as well.
I use Paint.NET and utilize a ton of layers when making a new piece of clothing, as well as several plugins for Paint.NET, including
the Smudge tool, Drop Shadow, Feather, Inner Shadow, and Object Shadow.
