:upset:
I’m doing some starling tests (because I haven’t really used it much before) and it seems Flash’s sprite sheet generator does not account for empty pixels
Texture packer does, and includes an offset value in the xml. This results in far more textures on a sheet, but even more important, performance is far greater.
Both tests have all the same game objects in a single 2048x2048 sprite sheet and 1 draw call.
flash pros sprite sheet = 39fps
texture packers = 52fps
Not to mention the wasted space might kick you into an additional sprite sheet causing another performance hit
