As we all know it's not easy to have all textures in power of two size. So a lot of memory is wasted when such textures are loaded into memory. Atlases helps with that, because it optimally packs all textures into texture of power of two size. In our case we could easily save 30% of memory. I'm wondering is there any way to reduce memory footprint using texture altases in pixi.js? Texture packages are produced with TexturePacker ( https://www.codeandweb.com/texturepacker ) and loaded following this pixi tutorial ( https://github.com/GoodBoyDigital/pixi.js/tree/master/examples/example%202%20-%20SpriteSheet ). The main problem is that creating PIXI.Sprite object with texture from atlas increases memory usage twice, because looks like it creates texture cache for sprite. I'm wondering maybe there is some way to eliminate texture cache and make PIXI.Sprite object just a metadata that defines rectangle in the atlas instead of copying texture rectangle from atlas to texture cache?
