Aftershock

Aftershock (New with Half-Life 2: Episode Two / Source 2007) This shader draws animated and scrolling refraction. It is able to smoothly fade out with alpha blending depending on its distance to the ground (per vertex; calculated with the material parameters $GroundMin and $GroundMax) and the dot product of the per vertex geometry normal and world view vector (scaled by $SilhouetteThickness). Furthermore this shader does solely support the vertexformat that studiomodels use.

Note:So far the only material that uses this shader is materials/models/props_combine/sphere.vmt. It can be found in episode two materials.gcf.

Shader specific parameters

$refractamount

$bluramount

Used to tweak the refraction effect.

$SilhouetteColor

$SilhouetteThickness

Scales the generic fade amount along the models edge.

$GroundMin

$GroundMax

Both describe an interval used to fade out the shader. Supposedly requires a custom material proxy to work correctly on non-stationary models.

Supported effects

• $normalmap
• $colortint
