From the apple documentation: "You can only request mipmaps if both texture sizes are two."
However, it is unclear whether SKTextures from SKTextureAtlas supports this function (since they are essentially slightly different in nature).
I ask a question because it is actually hard to see what something is getting from the results.
At first, SKTexture of SKTextureAtlas does not support mipmapping. Secondly, sometimes mipmapping doesn’t even work with regular SKTexture, it strongly depends on how it is nested inside the node structure.
