Template:Shaderparam It provides diffuse reflections, masked by a texture to control its intensity per-texel. For a full explanation, see Phong materials.
Note:Phong shading for LightmappedGeneric and WorldVertexTransition is only available in . It requires the material to be lit by a env_cascade_light entity to work properly, and uses the dynamic shadows generated by it as a mask on top of the traditional phong masking.Note:Phong shading for LightmappedGeneric is also available in .Syntax
$phong <bool>
Note:All parameters in the following example must be specified in the material, otherwise Phong shading won't show up at all, except in .- Todo: Other games that don't require all phong parameters present (likely Portal 2 and up)
