	'''Node Description and Purpose:''' Heightfield Merge allows you to merge two heightfields together based on simple settings that control the amount of heightfield mixing and the type of mixing method used.

			== Overview ==
			Heightfield Merge allows you to merge two heightfields together based on simple settings that control the amount of heightfield mixing and the type of mixing method used.
