[[Tool textures]] are used, mostly by the tools but sometimes by the engine, to perform special tasks. They can easily be found in [[Hammer]] by using "tools\" as a filter in the [[Hammer Texture Browser|texture browser]].

Anyone can make their very own tool texture, by utilizing available [[Material Map Compile Flags]], such as <tt>%compilenonsolid 1</tt>, <tt>%compileDetail 1</tt> and <tt>%compilenodraw 1</tt> for a tool texture which is not solid, does not cut [[visleafs]] and is invisible.

A <code>%tooltexture</code> may also be set, which is only to be seen in Hammer, while the <tt>$basetexture</tt> is seen in-game; however, the self made tool textures must be shipped with the map, else they might not work.


{{tip|[[WiseClipped]] gives a tutorial on using many of the Source Tool textures shown below.}}
{{note|All tool textures that are assumed to be texturing an entity work exactly like ordinary textures if applied to world brushes instead. As this makes them useless for world brushes, their visibility as world brushes is irrelevant. Also, many tool textures cut [[visleafs]]. If you aren't texturing an entity, you should tie the brush to {{ent|func_detail}} or {{ent|func_brush}} for [[Optimization_(level_design)|optimization]].}}
{{note|Some games may have outdated or obsolete tool textures in the "Dev" folder, such as <tt>dev/dev_windowportal</tt> in {{l4dseries}}.}}
{{note|Next to tool textures, there are also brush entities, which can perform tasks similar to tool textures.<br>For example, {{l4dseries}} have <code>Clip</code> for both teams, <code>Player Clip</code> for survivors and <code>NPC Clip</code> for infected; however, it also has {{ent|func_playerinfected_clip}} just for player controlled infected.<br>If you cannot find a tool texture fit for a task, perhaps the game you're mapping for has a brush entity for that.}}
{{note|This page is for tool textures as used in Source 1.<br>For tool textures used in GoldSrc titles, see [[Tool textures (GoldSrc)]].<br>For tool textures used by Source 2 titles, see [[Tool textures (Source 2)]].}}

===General—Common===
These tool textures are available in every Source engine game.<br>
Some of these textures have special function in some games. These special functions are noted by having the game's icon listed in the description. Such as {{css}},{{csgo}},{{l4d}},{{l4d2}}, ect.

| {{confusion|This is the <tt>Tools/ToolsBlack</tt> texture, not the <tt>Halflife/Black</tt> 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.<br>
An example of its use is in the "space" backgrounds during the G-Man monologues in {{hl2|2}} or for crude buildings in the 3D Skybox.<br>
Uses {{ent|UnlitGeneric}} in: {{hl2}} {{portalseries}} {{as}} <br>
Uses {{ent|LightmappedGeneric}} in: {{csseries|src=1}} {{l4dseries}}<br>
While in most games, the different shader has no impact, it might have a different function in other games. In that case, you may want to use <code>vgui/black</code> instead or make your own tool texture.

| 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 [[npc_antlion|antlion workers]], will still get through.<br>
To allow NPCs and their [[line of sight]] to pass through, turn the brush into a {{ent|func_brush}} with its <tt>Solidity</tt> keyvalue set to a solid state.<br>
{{csgo}} Use <code>blockbullets_cs</code> variant, which correctly stops bullets even with 1 unit thickness.

 -->Not drawn in game, seals [[leak]]s, 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.<br>{{portal}} Portals can be placed on it, but not in {{portal2}}. Use Nodraw Portalable instead if this behavior is desired.
{{note|The "glass footsteps" version of this texture in {{portal2}} does not [[seal]] maps.}}
{{note|While no lightmap data is generated on nodraw faces, nodraw brushes still cast shadows.}}
{{note|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.}}

These tool textures are available in every Source engine game.<br>
Some of these textures have special function in some games. These special functions are noted by having the game's icon listed in the description (such as {{css}},{{csgo}},{{l4dseries}}, ect.).

== Miscellaneous ==
These are textures that have a special use, sometimes only seen in one single game.

Some of these textures are not even "real" tool textures, as they do not possess any [[Material_Map_Compile_Flags|Compile Flags]], but they have some important use that no other texture available can do.

| Light is not blocked by this texture, except in {{csgo}}.<br>
Despite being in the <tt>Materials/Tools</tt> folder, this is not a tool texture. It has no abilities. It is simply an invisible texture used for [[Clip_texture|displacement clipping]], where you make an invisible displacement instead of a clip brush because making intricate clip brushes is difficult.<br>

Creates metal sparks when shot, but bullets pass through.<br>
Does not seal maps.<br>
{{tip|You may want to edit the VMT to add <code>%CompileDetail 1</code> to prevent it from cutting visleaves, which makes it much more useful. Alternatively, tie it to a {{ent|func_detail}} or other entity.}}

| This is a special tool texture, intended to prevent [[VMEX]] from decompiling any maps using this custom tool texture. [[BSPSource]] ignores this, rendering it useless.

Used with {{ent|func_brush}} to make it non-solid and fade away when approached.<br>
It being <tt>UnlitGeneric</tt> makes it seems as if it were glowing in a warm color, but is not listed in {{ent|lights.rad}}, so it won't actually emit any light for [[VRAD]] to compile.<br>
Only used in C8M2_Subway behind the three windows to the right of the entrance of the end map saferoom building, to simulate glowing light in a room.<br>

{{Warning|Does not work as intended on [[world brush]]es and {{ent|func_detail}}s as they have no origin: In-game, the {{ent|$alpha}} is either equal to the <tt>$alpha</tt> of the closest functioning application of this material on screen or - if there is none - the <tt>$alpha</tt> remains "stuck" at some value, no matter the proximity.}}
