I'm sure you've had this countless times; it sounds like a run-of-the-mill question though I can't find anything to help me.
How do I create skins for my characters? Please help! And how do I apply them? What should I save them as?
Are you say, about in a wrong type of editor's forum?
Coz AGS characters don't have "Skins", they compose of sprites, which are their walking, talking, thinking, idle etc. frames, each one as a single image, all sprites of one animation in one same size, preferably, so the character don't seem to jump around while talking, walking etc.
Just draw the sprites and import then in the AGS sprite manager, then set them into views, and set the views for your characters, and set other character protopies.
