 			If [code]true[/code], depth mapping is enabled (also called "parallax mapping" or "height mapping"). See also [member normal_enabled].
+			[b]Note:[/b] Depth mapping is not supported if triplanar mapping is used on the same material. The value of [member depth_enabled] will be ignored if [member uv1_triplanar] is enabled.
