What are atlases used for? https://www.sharetextures.com/atlases https://www.sharetextures.com/atlases

  Before bindless became a thing (and it's not yet standard with for example WebGL) then doing extra render calls just to change active textures could be an quite expensive operation. Thus a texture atlas is useful to be able to batch a lot of geometry into the same call (Also useful for 2d-like animations). https://en.wikipedia.org/wiki/Texture_atlas https://en.wikipedia.org/wiki/Texture_atlas

  Atlases are a set of small elements grouped together in one asset. It's usually used for trees and terrain objects.
