Let's take an overview of game asset creation. So let's think about all the things that make up a video game. Well, we've got sounds, images or textures, 3D models for characters or props, and scripts that can control interaction. All of these things are known as game assets generally. Now you might have heard this term a game engine. Well what is a game engine? A game engine is a software that combines input from the user with other assets like scripts and sounds to create real- time renderings which basically lead to your gameplay and fun video games are all about real-time rendering.
If you've ever tried to play a video game on a slow computer you might know what I am talking about. Video games that are responsive to user input, even games that are still difficult or challenging, are much more engaging than video games that are slow or unresponsive. Now in order for a computer that's rendering a video game to be responsive to user input, the game assets have to be rendered quickly. This means they must be optimized for low memory usage. So image resolutions for textures have to be relatively low. Also 3D models can't be too complex. So if you have experience creating models in Maya for still renders, for example, you might be used to working with higher resolutions and higher poly counts in your models. That's okay.
We will go over some specific techniques to prepare a character model asset for real-time rendering in the next few chapters.
