 			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.

 			If [code]true[/code], direction of the binormal is flipped before using in the depth effect. This may be necessary if you have encoded your binormals in a way that is conflicting with the depth effect.
