This page lists all known limitations of the GeoMod engine and maps built using RED level editor.

Map Limits

• This table lists all known limits that you need to keep in mind when making any type of level.
• There's no guarantee that your map won't perform poorly or crash for other reasons, even if these limits have not been explicitly exceeded.
• Please note that only a few of these limits were officially documented by Volition, the rest were discovered through experimentation. It's possible additional limits exist that should be added to this list, we just haven't found them yet.
• The de facto standard RF server and client version Dash Faction removes or increases a number of these limits.
  • In cases where Dash Faction has removed or increased a limit, the default limit is indicated with (RF), and the Dash Faction limit is indicated with (DF).

Element	Limit	Notes
Objects	1024 (RF), 65536 (DF)	General limit on total objects - note though that not all object types count toward this limit. Entities, corpses, clutter, items, triggers, events, keyframes, targets, and possibly more, all do.
Corpses	30 (RF), Unlimited (DF)	Dead entities in corpse pose. Counts both pre-placed corpses and corpses created by entities dying during gameplay.
Ambient sounds	25	Maximum number of ambient sounds that can play simultaneously. Includes both Ambient Sound objects and entity fly sounds as specified by "$FlySnd" in entity.tbl. When limit is reached, newly created ambient sounds will not play.
Faces/Polygons	10500	Counts all polygons on geometry (brushes) in a level. Note that this is a "soft limit", and nothing bad will necessarily happen simply as a result of exceeding this limit. (the RED console will turn red in color, though)
Face Vertices	50400	Note that this is a "soft limit", and nothing bad will necessarily happen simply as a result of exceeding this limit. (the RED console will turn red in color, though)
Vertices	13650	Counts all vertices on geometry (brushes) in a level. Note that this is a "soft limit", and nothing bad will necessarily happen simply as a result of exceeding this limit. (the RED console will turn red in color, though)
Lights	1100	RED will crash if this limit is exceeded.
Lights on a surface	64	If more than 64 lights are attempting to illuminate a single surface, that surface will turn pink. You can fix this by reducing the number of lights affecting the surface, or breaking up the surface so it's more than a single lightmap. Note that coplanar faces are merged together at build time to form a single surface, so if you're attempting to break it up for this reason, you must either use portals, or create a minor change in elevation. Also note that the true area of effect for a spotlight is based up on the range being used to determine the diameter (diameter = range X 2).
Items	200	Includes pickups, CTF flags/bases, CTF banners, etc. If you exceed 200 items, the game will stop creating them after the 200th. Dropped items by killed players/AI also count as objects, but don't count toward the 200 item limit.
Multiplayer Respawn Points	32	If you exceed 32 multiplayer respawn points, the game will ignore any beyond the 32nd.
Particle Emitters	128	If you exceed 128 particle emitters, your level file will become corrupt.
Green/red boxes around switches	32	If you have more than 32 switches in your map that should have green/red boxes, the box will only appear for 32 of them (the others will continue to function properly, just without the visible box).
Total Decals in a level	96/128 (RF), 384/512 (DF)	*Hard limit is absolute maximum number of decals. Soft limit is the limit after which decals begin to fade away. For decal objects placed in the editor, decals will stop being created after soft limit, and you risk level file corruption if you exceed hard limit. *For total number of decals, stock game has 96 soft limit, 128 hard limit. Dash Faction has 384 soft limit, 512 hard limit. *Additional limits: **Total decals in a single room: 40/48 (RF), 96/127 (DF) **Total weapon impact decals: 14/16 (RF), 48/64 (DF) **Total GeoMod decals: 30/32 (RF), 96/127 (DF) **Total decals on solids: 40/48 (RF), 96/127 (DF) *In the default RED editor (non-Dash), you'll get a pop-up warning when saving your level if it contains >64 decal objects. This was a hard limit for PS2 maps.

Savegame Format Limits

• This table lists all limits specific to the savegame file format.
• If you exceed these limits, your map may still initially load correctly, but players will experience issues when using the savegame system (including quicksaves and autosaves). For this reason, you should ensure any single player maps you create do not exceed these limits.
• For multiplayer maps, you can effectively ignore this table.

General Engine Limits

• This table lists game and engine limits that aren't specific to any of the other limit categories above.

Element	Limit	Notes
Bullets/Projectiles	Unknown (RF), Unlimited (DF)	Produced by weapon fire (players and AI). Exists until the $Lifetime value is exceeded, the bullet impacts something, or the projectile explodes.
Loaded Packfiles	256 (RF), Unlimited (DF)	Includes all .vpp packfiles loaded by the game. These are used to store custom maps, clientside mods, etc. Without Dash Faction, the game will ignore any .vpp packfiles after the 256th.
Files within Packfiles	13500 (RF), Unlimited (DF)	Includes all files within all .vpp packfiles loaded by the game. Without Dash Faction, the game will stop loading files in packfiles after the 13500th.
