My First Game: How many UV layouts should I create?
I'm in the process of creating my own video game using the skills I've learned from CGCookie. I have no formal education in video game development. Please excuse my lack of knowledge, everything I know involving video game development I've picked up from CGCookie, Youtube or some random corner of the internet.
I imagine this will be the first of many questions.
I know how to UV unwrap models and lay them out in the UV editor. I'm conscious to conserve space and pack the UV's as tightly as possible while considering pixel density.
What I'd like to know (on average) is how many maps should I layout? I would imagine most video games need to use more than one UV map for their game assets. For a one-man dev team, how many UV maps should I use? Roughly... ballpark?
