Template:Shaderparam 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.
Note:Since Source 2007, 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 disabled since due to conflicts with cascade shadow mapping.Important:In Black Mesa half-lambertian for new light is broken. The result is that meshes with $phong or $halflambert get lit from ALL sides perpendicular to newlights, including ones with opposing normals. If you want to use $phong or $halflambert - you are able to fix this with adding in your VMT material parameter "$halflambert_gbuffer_off" "1".Syntax
