<constant name="SPECULAR_SCHLICK_GGX" value="0" enum="SpecularMode">
Default specular blob.
[b]Note:[/b] Forward+ uses multiscattering for more accurate reflections, although the impact of multiscattering is more noticeable on rough metallic surfaces than on smooth, non-metallic surfaces.
[b]Note:[/b] Mobile and Compatibility don't perform multiscattering for performance reasons. Instead, they perform single scattering, which means rough metallic surfaces may look slightly darker than intended.

<constant name="SPECULAR_TOON" value="1" enum="SpecularMode">
Toon blob which changes size based on roughness.
