	'''Height multiplier:''' This parameter multiplies the heights from the heightfield. The default value of 1 will leave the heights unchanged. A value of 2 will double the heights. A value of 0.5 will make them half as high.		'''Height multiplier:''' This parameter multiplies the heights from the heightfield. The default value of 1 will leave the heights unchanged.

	'''Flatten surface first:''' If this is checked the planet surface underneath the heightfield is flattened before the heightfield displacement is applied, and the displacement is treated as absolute Y position. This has the effect of replacing all prior input surface displacement with the displacement produced by this shader and also eliminates the curvature of the planet. '''Border blending''', '''Blend by heightfield''' and '''Blend by shader''' affect the strength of ~~this replacement~~. If it is unchecked, the this surface shader's displacement is additive, like most displacement shaders in Terragen. You may need to uncheck '''Flatten surface first''' if you want the heightfield to follow the curvature of the planet or if you are stitching adjacent heightfields with '''Stitchable border''' checked.

	'''Interpolation method:''' This controls how the heightfield values are interpolated inbetween actual height values. The Catmull-Rom method is the default and is the best all round method. The following images show the effect of the different interpolation methods on a heightfield. Fractal detail was turned off for these images to show the heightfield more clearly. Click on any of the images to see larger versions.		'''Interpolation method:''' This controls how the heightfield values are interpolated inbetween actual height values.
