{{subpage|[[Material map compile flags]]}}
Compiles brushes textured with this material as having '''ladder''' [[Contents flags|contents]], meaning players will be able to climb up it. In some games, the material should be applied to a [[func_ladder]] brush entity in order for the navigation mesh to recognize it and to allowing [[NPC]]s to climb the ladder.<br>
Materials with this flag are visible to players, unless [[%compilenodraw]] is also used. All ladders found so far also make use of [[%compilepassbullets|%CompilePassBullets]], as this function is not inherited by %CompileLadder already.

{{note|Due to how contents flags work, giving a brush ladder contents will cause all faces of the brush to be climbable.
{{workaround|In {{css}}{{inline note|name=And others games?}} if only one brush face is desired, you can add the <code>ladder</code> $surfaceprop to a material which will make only that brush face climbable.}} }}

===Examples===

'''tools/ToolsInvisibleLadder.vmt''' is a ladder that is not visible to players.
<source>
"LightmappedGeneric"
{
	"$basetexture" "Tools/toolsinvisibleladder"
	"%compilenodraw" 1
	"%compilepassbullets" 1
	"%compileladder" 1
	"%keywords" "airexchange,borealis,c17downtown,c17industrial,c17sewers,c17skyscraper,c17trainstation,combine,kraken,wasteland"
}</source>

An improved version that does not cut visleaves would look like so:
<source>
"LightmappedGeneric"
{
	"$basetexture" "Tools/toolsinvisibleladder"
	"$translucent" 1
	"%compileladder" 1
	"%compiledetail" 1
	"%compilenodraw" 1
	"%compilepassbullets" 1
}</source>

'''Metal/MetalLadder001a.vmt''' is visible to players.
<source>"LightmappedGeneric"
{
	"$basetexture" "Metal/metalladder001a"
	"$surfaceprop" "metal"
	"%compileladder" 1
	"$alphatest" 1
	"%compilepassbullets" 1
}</source>

'''{{l4dseries}}Tools/Climb_Versus.vmt''' is only visible to infected players, due to the proxies.
