Map Data Assets (.#map)

The .#map file format (stored in rage::fwMapDataStore) is a PSO/RSC-style format expecting a CMapData (project-specific, inherits from rage::fwMapData) root element.

Formerly, this would be placed in a .#pl file. .#map is also known as .imap in North naming conventions.

The #map format has the following structure:

CMapData

Entity flags

flags

Flag Decimal Meaning
0x1 1 Allows full rotation for entity.
0x2 2 Do not delete the entity during streaming cleanup (out-of-memory situations) even if the entity is invisible. Usually used for dynamic objects where deleting the entity would result in moving the object back to its original position.
0x4 4 Disables embedded collision, works for entites using 0x20000/131072 archetype flag.
0x8 8 Used for entities linking to another entity in parent #map file.
0x10 16 Unknown usage.
0x20 32 This flag enables a indestructibility for archetype, making it static for props.
0x40 64 Unknown usage.
0x80 128 Unknown usage.
0x100 256 Unknown usage.
0x200 512 Disables embedded light source for #dr models.
0x400 1024 Unknown usage.
0x800 2048 Unknown usage.
0x1000 4096 Unknown usage.
0x2000 8192 Unknown usage.
0x4000 16384 Unknown usage.
0x8000 32768 Unknown usage.
0x10000 65536 Unknown usage.
0x20000 131072 Unknown usage.
0x40000 262144 Disable archetype extensions for #dr models.
0x80000 524288 Unknown usage.
0x100000 1048576 Unknown usage.
0x200000 2097152 Unknown usage.
0x400000 4194304 Disables sun shadow for entity.
0x800000 8388608 Disables entity but sun shadow is casted.
0x1000000 16777216 Entity will not cast reflections.
0x2000000 33554432 Marks that entity is a interior proxy.
0x4000000 67108864 Marks that entity doesn’t render in water reflections.
0x8000000 134217728 Marks that entity is a reflection proxy.
0x10000000 268435456 Unknown usage.
0x20000000 536870912 Marks that entity is a mirror proxy.
0x40000000 1073741824 Unknown usage.
0x80000000 2147483648 Unknown usage.
