I am creating this and other stuff for demo reel to show to video game companies, tryin to get me a job.

In video-games, how are these "separate" objects made? Are they just separate geometry just sitting on top of the main body? Or are they actually single geometry for entire body + other stuff? Like hats and shoes and stuff?

Thx.

btw, The Game Artist's Guide to Maya book by McKinley helped a lot while making this. didn't follow step by step, i was rushin.
