Hi!
I've managed to create a spriteCollection that supports tk2dSystem.Currentplatform 1x, 2x and 4x. This all works great and very intuitive (thank you for that!). However I've found a small issue with my current setup:
Since I've added ALL my PNG's to the spriteCollection (including multiple background images (of 2560x1600 in the 4x category)) my spriteSize is significant (the 4x spriteSize is 4096x8192), which causes an all black game on my iPad Retina (the game runs perfectly on my iPad2 though cause the 2x spriteSize is smaller, oh the irony).
I've removed the background images from the spriteCollection and now everything runs perfectly (aside from the game not having backgrounds of course).
My question is: how can I use these backgrounds (with the 1x 2x and 4x platform-support in mind) without them adding up to the spriteCollection. Can I use SpriteFromTexture for this? And if so: how? (I've already tested this using my current setup, but it just takes the 1x version).
Keep up the good work and thank you in advance!
