What is the best way to store sprites in Unity?

Question

Unity

I have a pixelated 2D GUI game with static objects and animations (via sprites).
How do I store all these sprites for optimization? (all these sprites on one canvas or static sprites on one canvas, and all animations separately or even each sprite on its own canvas)

Answer 1

They are atlases, not canvases. Group them by use. If you have 10 sprites in your location and they all lie in different atlases, then all these atlases will be forced to load into memory. Therefore, it is beneficial to keep together those sprites that are used together. There is not even anything wrong if the same sprite is in several atlases.
