+			If [code]true[/code], the refraction effect is enabled. Refraction distorts transparency based on light from behind the object. When using the GLES3 backend, the material's roughness value will affect the blurriness of the refraction. Higher roughness values will make the refraction look blurrier.

-			Specifies the channel of the [member ao_texture] in which the ambient occlusion information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored metallic in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.
