Resource limits

Mod API v1 applies conservative limits before allocating or constructing runtime content. These are safety ceilings, not performance targets.

Resource	Limit
Pack directories scanned	1,024
manifest.json	256 KiB
JSON content files per pack	4,096
Each loader-owned content JSON	1 MiB
Main Tiled map JSON	16 MiB
Each referenced Tiled object template	1 MiB
Resolved Tiled object templates	4,096, with at most 16 nested references
Tile cells in one layer	1,000,000
PNG file	32 MiB, 8,192 pixels on either side, and 32 megapixels decoded
Weapon effect PNG	16 MiB before decode
WAV/OGG file	64 MiB
.capmod archive	256 MiB on Windows/Android; 32 MiB on WebGL
Catalog dependency install batch	512 MiB on Windows/Android; 64 MiB on WebGL
Weapon sprite-animation frames	120 per clip and four named clips
Stage spawners	256; 64 enemy IDs per spawner

The JSON Schemas contain more specific array and numeric limits. Authors should stay substantially below these ceilings, particularly for decoded textures, animated tiles, particle counts, and simultaneous enemies. Passing validation does not guarantee acceptable frame time or memory usage on every device. See Windows, Android, and WebGL for platform packaging and verification status.
