Post-Baking Memory Optimization

Since version 1.2.0, Mirage includes an Impostor Optimizer (Window → Mirage → Impostor Optimizer) to change the texture atlas formats and downsample the Albedo, Normal and Mask atlases independently.

This is especially useful when building for iOS — where DXT compression is not supported — or to reduce the final build size.

⚠ These optimizations change the prefabs directly and are NOT REVERSIBLE. Fine-tune on impostor copies first.

You can drop as many impostors as you want into the drop zone; the same settings are applied to all of them sequentially.
