	~~'''Node Description and Purpose:'''<br />~~
	The Displacement shader takes the values generated by the connected function nodes and turns them into displacement. You can connect any sort of function nodes to the input but the input value is converted to a scalar.

			==Overview==
			The Displacement shader displaces a surface by the values from any shader or function nodes assigned to its function input. Values from the assigned shader or function nodes are converted to scalar data.

	'''~~Node Type~~:''' Displacement ~~Shader~~<br />
			'''Settings:'''


			*'''Name:''' This setting allows you to apply a descriptive name to the node, which can be helpful when using multiple Displacement shader nodes in a project.


			*'''Enable:''' When checked, the node is active and the Displacement shader will be applied to the surface. When unchecked, the node is ignored.


			*'''Function:''' This setting allows you to assign shader or function nodes to use as displacement for the surface.

			</ul>


	'''~~Settings~~:'''		*'''Displacement direction:''' This popup has 5 options which allow you to choose the direction in which the displacement is applied in. Options that "(requires computed normal)" must have a Compute Terrain or Compute Normal node connected somewhere above the Surface Layer in the network to work properly. The popup has the following options

	~~<li>~~		[[File:SurfLay_05_DisplacementDirectionOptions_GUI.png\|436px\|Displacement direction options]] <br />
	~~'''Function~~:~~''' You connect the function node(s) which generate the displacement values to this input~~.
	~~</li><li>~~
	~~'''~~Displacement direction~~:''' This popup list allows you to choose the direction that displacement is applied in. Any~~ options ~~in the popup list that have "(requires computed normal)" require that there be a [[Compute Terrain~~]] ~~or [[Compute Normal]] connected somewhere above the node in the network to work properly. The popup has the following options:~~

	~~<li>~~		<u>Along vertical:</u> Displacement happens along the normal of the underlying planet or 3D object’s geometry. <br />
	<u>Along vertical:</u> Displacement ~~will happen~~ along the ~~existing normals~~ of the underlying ~~object (i.e. the~~ planet or ~~a model) prior to any other displacement having been applied~~.		<u>Along normal:</u> Displacement happens along the current surface normal. <br />
	</~~li><li~~>		<u>Vertical only (requires computed normal):</u> Displacement only happens along the normal of the underlying planet or 3d object’s geometry.
