Atlas Maker (v3)

Paste CSV or upload a file. Supports Aspect Ratio per row (e.g. 1:1, 2:1, 1:2). Toggle the Power-of-Two requirement on/off. Elements are maximized to fit the atlas while respecting aspect and other constraints.

1) CSV Input

Headers must be present: Texture Name,size,Aspect Ratio. Aspect Ratio defaults to 1:1 if omitted.
Or drag & drop a .csv file here

2) Atlas Settings

Enter a single square size (e.g. 2048) or W×H (e.g. 4096x2048).
Advanced
When PoT is on and a ratio isn't a power-of-two fraction (e.g. 3:2), the tool keeps the exact aspect but may not be able to make both sides PoT. A warning will be shown.
