Assets explained

What is an asset?

An asset is a specific, objectified concept in the game that can be highly detailed like a blade of grass, or larger like a building, or intangible like sound effects. Unity defines an asset as, "Shorthand for anything that goes into a video game โ€“ characters, objects, sound effects, maps, environments, etc." Every asset is defined in a set of normalized asset files that describe its relationship to the game, other assets, and itself.

The following list contains file formats that are used to compose visual assets such as vehicles and weapons.
