$halflambert is a material shader parameter for the VertexLitGeneric, Teeth, EyeRefract, VortWarp, and Infected (shader) shader available in all 
Source games. It is a boolean parameter that enables half-lambertian lighting, which wraps lighting further around a model to prevent it from losing definition. It only works on models.
Important:In stock shaders for to , half-lambertian lighting is forcibly enabled on VertexLitGeneric regardless of $halflambert setting when $phong is enabled, unless $phongdisablehalflambert(in all games since ) is enabled.Note:This parameter is forcibly disabled since due to conflicts with cascade shadow mapping.Important:Not designed for static props:
- Does not work on static props which have lighting baked per-vertex or into lightmaps in stock VRAD; this could be achieved with a custom VRAD.
- Shadows cast by static props will always be full-lambertian. This could potentially be worked around by using an %alphatexture with half opacity.
