Choose sprite atlases using memory and draw-call evidence
The practical problem
Hundreds of sprites as separate assets add request overhead, but one oversized atlas can consume GPU memory even for unseen animations.
Implementation protocol
Group atlases by scene lifetime and measure both transfer bytes and decoded RGBA area. Include padding around sprite borders and test fractional scaling.
Worked scenario
A 1024×1024 RGBA atlas requires roughly four megabytes before mipmaps; two unused atlases held in memory may cost more than separate small files.
What could go wrong
Aggressive packing can cause texture bleeding at small scales.
Acceptance criteria
Test art sharpness, resident memory and batching gains before merging sheets.
