I use the the resource system to create my items and instead of having individual sprites for every single items I wanted to have an atlas texture. However if you change the region of an atlas Texture, every sprite of every item changes too, so I make them all unique and that sounds like a really bad idea to me.... unfortunately I don't have a better idea. So how bad will it look like if I have later on 1000 items, each unique Atlas Texture?
"Make Unique" on Atlas Texture, how much impact on memory?
