Keeping Record

Just to keep record of the other useful mask list:

MASK_ALL				(0xFFFFFFFF)
MASK_SOLID				(SOLID | MOVEABLE | WINDOW | MONSTER | GRATE)
MASK_PLAYERSOLID			(SOLID | MOVEABLE | PLAYERCLIP | WINDOW | MONSTER | GRATE)
MASK_NPCSOLID				(SOLID | MOVEABLE | MONSTERCLIP | WINDOW | MONSTER | GRATE)
MASK_WATER				(WATER | MOVEABLE | SLIME)
MASK_OPAQUE				(SOLID | MOVEABLE | OPAQUE)
MASK_OPAQUE_AND_NPCS			(MASK_OPAQUE | MONSTER)
MASK_VISIBLE				(MASK_OPAQUE | IGNORE_NODRAW_OPAQUE)
MASK_VISIBLE_AND_NPCS			(MASK_OPAQUE_AND_NPCS | IGNORE_NODRAW_OPAQUE)
MASK_SHOT				(SOLID | MOVEABLE | MONSTER | WINDOW | DEBRIS | HITBOX)
MASK_SHOT_HULL				(SOLID | MOVEABLE | MONSTER | WINDOW | DEBRIS | GRATE)
MASK_SHOT_PORTAL			(SOLID | MOVEABLE | WINDOW)
MASK_SOLID_BRUSHONLY			(SOLID | MOVEABLE | WINDOW | GRATE)
MASK_PLAYERSOLID_BRUSHONLY		(SOLID | MOVEABLE | WINDOW | PLAYERCLIP | GRATE)
MASK_NPCSOLID_BRUSHONLY			(SOLID | MOVEABLE | WINDOW | MONSTERCLIP | GRATE)
MASK_NPCWORLDSTATIC			(SOLID | WINDOW | MONSTERCLIP | GRATE)
MASK_SPLITAREAPORTAL			(WATER | SLIME)
MASK_CURRENT				(CURRENT_0 | CURRENT_...)

MASK_WATERWORLD				(SOLID | WINDOW | GRATE | SLIME | WATER | MOVEABLE | MONSTERCLIP)
					In binary: 100100000000111011, so the above is my best guess

And content:

You can also create your own masks by using CONTENTS_* enumerations.

// lower bits are stronger, and will eat weaker brushes completely
#define	CONTENTS_EMPTY			0		// No contents

#define	CONTENTS_SOLID			0x1		// an eye is never valid in a solid
#define	CONTENTS_WINDOW			0x2		// translucent, but not watery (glass)
#define	CONTENTS_AUX			0x4
#define	CONTENTS_GRATE			0x8		// alpha-tested "grate" textures.  Bullets/sight pass through, but solids don't
#define	CONTENTS_SLIME			0x10
#define	CONTENTS_WATER			0x20
#define	CONTENTS_MIST			0x40
#define CONTENTS_OPAQUE			0x80	// things that cannot be seen through (may be non-solid though)
#define	LAST_VISIBLE_CONTENTS	0x80

#define ALL_VISIBLE_CONTENTS (LAST_VISIBLE_CONTENTS | (LAST_VISIBLE_CONTENTS-1))

#define CONTENTS_TESTFOGVOLUME	0x100

// unused 
// NOTE: If it's visible, grab from the top + update LAST_VISIBLE_CONTENTS
// if not visible, then grab from the bottom.
#define CONTENTS_UNUSED5		0x200
#define CONTENTS_UNUSED6		0x4000

#define CONTENTS_TEAM1			0x800	// per team contents used to differentiate collisions 
#define CONTENTS_TEAM2			0x1000	// between players and objects on different teams

// ignore CONTENTS_OPAQUE on surfaces that have SURF_NODRAW
#define CONTENTS_IGNORE_NODRAW_OPAQUE	0x2000

// hits entities which are MOVETYPE_PUSH (doors, plats, etc.)
#define CONTENTS_MOVEABLE		0x4000

// remaining contents are non-visible, and don't eat brushes
#define	CONTENTS_AREAPORTAL		0x8000

#define	CONTENTS_PLAYERCLIP		0x10000
#define	CONTENTS_MONSTERCLIP	0x20000

// currents can be added to any other contents, and may be mixed
#define	CONTENTS_CURRENT_0		0x40000
#define	CONTENTS_CURRENT_90		0x80000
#define	CONTENTS_CURRENT_180	0x100000
#define	CONTENTS_CURRENT_270	0x200000
#define	CONTENTS_CURRENT_UP		0x400000
#define	CONTENTS_CURRENT_DOWN	0x800000

#define	CONTENTS_ORIGIN			0x1000000	// removed before bsping an entity

#define	CONTENTS_MONSTER		0x2000000	// should never be on a brush, only in game
#define	CONTENTS_DEBRIS			0x4000000
#define	CONTENTS_DETAIL			0x8000000	// brushes to be added after vis leafs
#define	CONTENTS_TRANSLUCENT	0x10000000	// auto set if any surface has trans
#define	CONTENTS_LADDER			0x20000000
#define CONTENTS_HITBOX			0x40000000	// use accurate hitboxes on trace
