I mean, there's a way to script it - you showimg the background as 0, then showimg pics1.png over that, in 64x64 (4096) pieces...but that hardly seems efficient. You could also TRY to cut the background into pieces that are the exact right size (per the level's Transparency Mask), but that might even be more work. Although...perhaps this is a job for the particle engine (cutting round corners on dynamically generated square images)?

But I'm talking to myself again...I don't have a tendency to make myself any clearer in so doing.
