| Has no effect on anything (except [[weapon c4|bomb]] in {{css}}). Skip faces are removed during compile, so a brush textured with Skip won't prevent leaks.
Useful in combination with Hint tool textures (to prevent the other sides from cutting vis) and as a tool in Hammer for grouping, moving and place-holding objects.
{{bug|hidetested=1|In {{css}}, skip brushes act as [[clip]] brushes for the [[weapon c4|bomb]].

=== Sky and Fog — Game-Specific ===
These tool textures are only available in specific Source engine games.

There are no game specific tool textures in this section.

== 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.

| 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 or 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.

It being {{mono|UnlitGeneric}} makes it seems as if it were glowing in a warm color, but is not listed in [[lights.rad]], so it won't actually emit any light for [[VRAD]] to compile.<br>
