Ru/Tool textures (Source)

Служебные текстуры используются для решения особых задач и создания специальных условий на карте. Найти их довольно просто. Достаточно вписать tools\ в поле Filter в окне обозревателя текстур.

Общие

Image	Name	Visible if world brush	Casts shadows	Cuts VIS leaves	Blocks NPC LOS	Solid to NPCs	Solid to player(s)	Solid to physics	Solid to bullets	Usage / Notes
	Black	Да	Да	Да	Да	Да	Да	Да	Yes (marks)	Примечание:This is the tools/toolsblack texture, not the halflife/black texture. This texture is often used for brushes that are far away and they are dark. It cannot be lit by any type of light, but is affected by fog color. An example of its use is in the "space" backgrounds during the G-Man monologues in Half-Life 2. Предупреждение:In and this texture is LightmappedGeneric use vgui/black instead.
	White	Да	Да	Да	Да	Да	Да	Да	Yes (marks)	Identical to tools/toolsblack texture only in white.
	White Arkane	Да	Да	Да	Да	Да	Да	Да	Н/Д	Acts the same as White, but for some reason is used instead.
	Block Bullets	Нет	Нет	Да	Нет	Да	Да	Да	Yes (No Marks)	Foremost solid to bullets, but also to NPCs and physics projectiles. It does not block all projectiles, though. Projectiles from NPCs such as the acid spit from antlion workers, will still get through. To allow NPCs and their line of sight to pass through, turn the brush into a func_brush with its Solidity keyvalue set to a solid state.
	Invisible	Нет	Нет	Да	Нет	Да	Да	Да	Нет	Solid to all objects and projectiles, not solid to bullets. Smokers, Boomers and Spitters can attack you through it, but neither survivors nor infected can pass it. Предупреждение:Solid to bullets in and
	(Invisible) Ladder	Нет	Нет	Да	Нет	Да	Да	Да	Нет	Used with func_ladder in the most multiplayer games except Half-Life 2 Deathmatch. Ladder will not work if used with func_ladder.
	Nodraw	Нет	Да	Да	Да	Да	Да	Да	Yes (No Marks)	Not drawn in game, seals leaks, and is skipped by VRAD. Blocks visibility if used on all surfaces of the same brush. Optimally, every face that can't be seen during normal gameplay should have this texture. Portals can be placed on it, but not in . Use Nodraw Portalable instead if this behavior is desired. Примечание:The "glass footsteps" version of this texture in does not seal maps. Примечание:While no lightmap data is generated on nodraw faces, nodraw brushes still cast shadows. Примечание:Despite common misconception, it is not necessary to use nodraw on faces that don't touch visleaves, as these are automatically removed by VBSP. This means faces that are outside the map and faces that are flush with another one.
	Origin	Н/Д	Нет	Нет	Нет	Нет	Нет	Нет	Нет	Leftover from GoldSource, where a brush with this texture was used to set the rotation origin of rotating entities. It is still functional in Source (overriding the entity's origin keyvalue), but no longer necessary. When placed outside of a brush entity, the compiler will fail with the error origin brushes not allowed in world. Not available in all branches.
	Block LOS	Нет	Нет	Нет	Да	Нет	Нет	Нет	Нет	Blocks the line of sight of NPCs and bots. mat_wireframe 1/2 will reveal that while this texture doesn't block visleaves, it draws crossing polygons, and them alone are capable of preventing the engine from rendering enveloped brushwork. This can be worked around through turning the Block LOS textured brush into a func_brush with its Solidity keyvalue set to a solid state. (A Block LOS func_brush can still be traversed in this state.)
	Block Light	Нет	Да	Нет	Нет	Нет	Нет	Нет	Нет	Casts shadows artificially. Only used at compile time by VRAD. Does not seal leaks. See more uses here.
	Trigger	Да	Нет	Нет	Нет	Нет	Нет	Нет	Нет	Used on Trigger and func_viscluster entities.

Optimisation

Image	Name	Visible if world brush	Casts shadows	Cuts VIS leaves	Blocks NPC LOS	Solid to NPCs	Solid to player(s)	Solid to physics	Solid to bullets	Usage / Notes
	Areaportal	Да	Нет	Да	Нет	Нет	Нет	Нет	Нет	Use with areaportals (func_areaportals and func_areaportalwindows). Can be used with other brush entities, such as some triggers.
	Hint	Нет	Нет	Да	Нет	Нет	Нет	Нет	Нет	This texture is used to instruct the compiler to cut visleaves.
	Skip	Нет	Нет	Нет	Нет	Нет	Нет	Нет	Нет	Has no effect on anything. Useful in combination with Hint tool textures. Skip faces are removed during compile, so a brush textured with skip won't prevent leaks. Also useful as a tool in Hammer for grouping, moving and place-holding objects.
	Occluder	Да	Нет	Нет	Нет	Нет	Нет	Нет	Нет	Used only for func_occluder entities.

Clips

Image	Name	Visible if world brush	Casts shadows	Cuts VIS leaves	Blocks NPC LOS	Solid to NPCs	Solid to player(s)	Solid to physics	Solid to bullets	Usage / Notes
	Clip	Нет	Нет	Нет	Нет	Да	Да	Нет	Нет	Solid to players and NPCs but not other objects. In Source 2013, it's also solid to item pickups like ammo packs but not dropped weapons. Solid to dropped C4. Features clip brush textures with different material types: Concrete, Dirt, Glass, Grass, Gravel, Metal, Metal Sand Barrel, Metal Grate, Metal Vehicle, Plastic, Rubber, Rubber Tire, Sand, Tile, Wood, Wood Basket, Wood Crate. See more about clip texture here.
	NPC Clip	Нет	Нет	Нет	Нет	Да	Нет	Нет	Нет	Solid to NPCs only. Solid to bots. Solid to infected only, but does not stop Smokers, Boomers and Spitters from attacking you through it.
	Player Clip	Нет	Нет	Нет	Нет	Нет	Да	Нет	Нет	Solid to players only. In Source 2013, it's also solid to item pickups like ammo packs but not dropped weapons. Solid to players and bots. Solid to dropped C4. Solid to the survivors only.
	Player Control Clip	Да	Да	Да	No?	Да	Да	Да	Yes (marks)	Available only in Source 2006 and earlier, but brought back in . It is obvious that this texture has to be tied to an entity to gain any special abilities, but what entity is not yet confirmed. Seems that it is necessary for func_vehicleclip. (See "player clip" above for the tool texture that restricts player movement.)
	Grenade Clip	Нет	Нет	Нет	Нет	Нет	Нет	Grenades only	Нет	Solid to grenades only.
	Stairs	Нет	Нет	Нет	Нет	Нет	Да	Нет	Нет	Functionally the same to player clip but allows for steeper angles when walking on, up to 63.4349488°.
	Drone Clip	Нет	Нет	Нет	Н/Д	Н/Д	Нет	Нет	Нет	Used to prevent drone getting stuck on complex geometry.
	Clip Xen Leaves Version	Нет	Нет	Да	Нет	Да	Да	Да	Нет	A special clip used for clipping the leaves in xen

Sky and fog

Image	Name	Visible if world brush	Casts shadows	Cuts VIS leaves	Blocks NPC LOS	Solid to NPCs	Solid to player(s)	Solid to physics	Solid to bullets	Usage / Notes
	Fog	Да	Нет	Да	Нет	Да	Да	Да	Yes (marks)	Подтвердить:Does not seem to work? (You can use this for func_smokevolume instead of the trigger texture but NOT for func_dustcloud.)
	Skybox	Нет	Нет	Да	Да	Да	Да	Да	Yes (No Marks)	This texture is used to make 3D skyboxes. Casts light if there is a light_environment entity in the map. Cannot be used in the same PVS as the toolsskybox2d tool texture. Things such as another area of a map will render on top of the skybox. An areaportal can stop this from happening, but it's generally better practice to add more scenery to cover the stuff that shouldn't be seen, reposition those things out of view, or just don't have an opening in that area.
	Skybox NoLight	Нет	Да	Да	Да	Да	Да	Да	Н/Д	Works identical to Skybox, but does not casts any light rays.
	2D Skybox	Нет	Нет	Да	Да	Да	Да	Да	Yes (No Marks)	Available only in Source 2007 and later. Use to make 2D skyboxes without displaying the 3D Skybox. Casts light if there is a light_environment entity in the map. Баг:Light cast from this texture can still be blocked by 3d skybox geometry.  [нужно проверить в ?] Cannot be used in the same PVS as the toolsskybox tool texture.
	SkyFog	Нет	Да	Да	Н/Д	Н/Д	Да	Н/Д	Yes (marks)	The SkyFog texture does not contain any properties. There is currently no existing corresponding Shader called "skyfog". (Generates error Error: Material "tools/toolsskyfog" uses unknown shader "SkyFog".) Подтвердить:It can be fixed to function properly if it's vmt settings are changed in the Source code and recompiled
	Fog Volume	Да	Нет	Нет	Нет	Нет	Нет	Нет	Нет	Available only in Left 4 Dead and later. Used in conjunction with multiple env_fog_controllers to change fog colours and densities in a level. Fog inside its volume will not appear to have different atributes when viewed from outside its volume, as it globally changes the appearance of all fog across the map when entered.

Portal 2

Image	Name	Visible if world brush	Casts shadows	Cuts VIS leaves	Blocks NPC LOS	Solid to NPCs	Solid to player(s)	Solid to physics	Solid to bullets	Usage / Notes
	Black cheap	Да	Да	Да	Да	Да	Да	Да	Yes (marks)	Identical to tools/toolsblack, the only difference is that uses special "black" shader. has a replacement that works with older engines. Нужно сделать: Find more about "black" shader
	Black noportal	Да	Да	Да	Да	Да	Да	Да	Yes (marks)	Identical to tools/toolsblack, the only difference is that Portals can't be placed on it.
	Black noportal nofog	Да	Да	Да	Да	Да	Да	Да	Yes (marks)	Identical to tools/toolsblack_noportal, the only difference is no fog.
	Black noportal skybox	Да	Да	Да	Да	Да	Да	Да	Yes (marks)	The same as tools/toolsblack_cheap
	Nodraw Portalable	Нет	Да	Да	Да	Да	Да	Да	Yes (No Marks)	Identical to Nodraw, the only difference is that Portals can be placed on this texture.

Miscellaneous

Image	Name	Visible if world brush	Casts shadows	Cuts VIS leaves	Blocks NPC LOS	Solid to NPCs	Solid to player(s)	Solid to physics	Solid to bullets	Usage / Notes
	Invisible Displacement	Нет	Нет	Нет	Нет	Да	Да	Да	Yes (No Marks)	Not actually a texture. It is the backside of a displacement. This side of the displacement will appear invisible, but solid. Light is not blocked by this texture, except for .
	Climb	Нет	Нет	Нет	Нет	Да	Да	Да	Нет	A ladder only for Infected. Not Visible to Infected Players during Versus. Use Climb Versus Instead.
	Climb Versus	Both (Visible to Infected)	Нет	Нет	Нет	Да	Да	Да	Нет	A ladder only for infected, must be used with func_ladder, otherwise it will be ignored by the navigation mesh editor and Special infected which do not require a navigation mesh to move.
	Dotted	Да	Нет	Да	Нет	Да	Да	Да	Yes (marks)	A face textured with this texture is rendered on top of all other brush geometry. Furthermore, a brush with Dotted on any face will not block visibility nor cull any face that it touches, meaning that any area enclosed in a Dotted-textured brush will not be removed from the map in any way.
	Dynamic Difficulty	Да	Да	Да	Да	Да	Да	Да	Yes (marks)	Solid to grenades. Tied to the trigger_dynamic_difficulty entity for the game's difficulty system.
	Interactive	Нет	Нет	Нет	Нет	Да	Да	Да	Yes (No Marks)	Utility texture tied to the ship_base_interaction brush entity to specify the only surfaces available for the player to interact with the entity
	Invismetal	Нет	Нет	Да	Нет	Да	Да	Да	Нет	Invisible texture, with metal surface properties. Simmilar to how Nodraw Metal Should have worked. Does not seal maps. Creates metal sparks when shot, but bullets pass through.
	Non-Interactive	Нет	Да	Да	Да	Да	Да	Да	Yes (No Marks)	Utility texture tied to the ship_base_interaction brush entity as a measure to help identify surfaces from which the player are unable to interact with said entity

	Func leaves	Да	Нет	Нет	Нет	Да	Да	Да	Н/Д	Used with the func_leaves entity to spawn leaves particles inside its volume.
	Vitrail Light	Да	Нет	Нет	Нет	Да	Да	Да	Н/Д	Purpose currently unknown, properly used with some type of brush entity.
	Gray	Да	Да	Да	Да	Да	Да	Да	Н/Д	Purpose unknown, just a grey texture.
	Waterbounds	Да	Да	Да	Да	Да	Да	Да	Н/Д	Used underwater when water meets the skybox.
	Block Bomb	Нет	Нет	Да	Да	Да	Да	Да	Да	Original purpose probably was to only block the C4 but it currently works just like a normal Clip brush.
	Hide	Да	Нет	Да	Нет	Да	Да	Да	Да	A gradient from transparent to black.
