How is the character generator made?

Question

Programming

I have long been interested in the question of how a generator is made when creating a game character. Of course, I don't need a very complex answer, I just want to know the surface.
Take Lineage 2 or World of Warcraft as an example. The choice is generally given three or four styles of something (face, body). And here is the question itself. Do developers somehow store these models with different views, and then load them according to the player's choice, or is everything a little simpler?

Answer 1

Character models are stored separately from skins (and, of course, from all ammunition: wrenches :), hammers, swords, axes, pistols, rifles, blasters and other items).
www.makehuman.org - you can make characters.
Sometimes it happens that they connect the head, torso, arms and legs through 4 (or 6) separate models, fastening them dynamically within the game. Then, each individual such element can have its own skin, etc.
Creating a dynamic rendering of a model inside a game is a non-trivial, labor-intensive, but quite real task.
