+- Supports Lambert, Lambert Wrap (half-Lambert), Oren-Nayar and Toon diffuse shading modes.
+- Supports Schlick-GGX, Blinn, Phong, Toon and Disabled specular shading modes.
 - Uses a roughness-metallic workflow with support for ORM textures.

 - Normal mapping.
-- *GLES3:* Parallax/relief mapping with automatic level of detail based on distance.
-- *GLES3:* Sub-surface scattering and transmittance.
-- *GLES3:* Proximity fade (soft particles).
+- Detail mapping for the albedo and normal maps.
 - Distance fade which can use alpha blending or dithering to avoid going through
   the transparent pipeline.
 - Dithering can be determined on a per-pixel or per-object basis.
+- *GLES3:* Parallax/relief mapping with automatic level of detail based on distance.
+- *GLES3:* Sub-surface scattering and transmittance.
+- *GLES3:* Refraction with support for material roughness (resulting in blurry refraction).
+  On GLES2, refraction is still functional but lacks support for material roughness.
+- *GLES3:* Proximity fade (soft particles).
 
 **Real-time lighting:**
 
 - Directional lights (sun/moon). Up to 4 per scene.
 - Omnidirectional lights.
 - Spot lights with adjustable cone angle and attenuation.
+- Specular energy can be adjusted on a per-light basis.
+- *GLES3:* Lighting is done with a single-pass forward approach.
+  By default, up to 32 omni light and 32 spot lights can be displayed per mesh resource.
+  If needed, this limit can be increased at the cost of increased shader compilation times and lower performance.
+  GLES2 uses a multi-pass forward approach to lighting, which doesn't have a
+  limit on the number of lights but is slower with many lights.
