Note:This shader parameter is also available in 
. In , it can also be used for UnlitGeneric.
Note:This shader is disabled by default in the 
SDK. It can re-enabled by modding.
Bug:In , using a projected texture on materials with this parameter will cause flickering. As a workaround, try to keep trees away from where player flashlights can reach. $halflambert may also partially fix the issue. [todo tested in ?]

Template:Shaderparam It morphs a material around using the parameters of an env_wind entity to give the appearance of tree leaves and foilage blowing in the wind. The subparameters of $treesway determine how much the env_wind entity should affect the morphing, and all of them (except $treeswaystatic) must be specified in order for the effect to work properly. This shader parameter assumes any model using it is facing upwards.
Note:This shader parameter is also available in . In , it can also be used for UnlitGeneric.Note:This shader is disabled by default in the SDK. It can re-enabled by modding.Bug:In , using a projected texture on materials with this parameter will cause flickering. As a workaround, try to keep trees away from where player flashlights can reach. $halflambert may also partially fix the issue. [todo tested in ?]- Todo: What about
$singlepassflashlightand$flashlightnolambert?
