Heightfield Layer

fields/heightfield-layer·v1.5.1

IN:2 OUT:1

SUMMARY

Heightfield Layer combines two height fields. It resamples the second input at the first one's sample positions by world position, so the two can differ in resolution and extent, and composites the chosen Source Layer onto a layer of the first with Replace, Add, Subtract, Difference, Multiply, Maximum, Minimum, Blend or Screen.

Base, layer and final scale and offset reshape each side before and after compositing, Clamp Minimum and Maximum limit the result, and the falloff restricts where the second field is applied. Outside the second field, or with no second input, the first height field passes through unchanged.

PARAMETERS

PAGELayer

Layer	Layer	The layer of the first input that receives the result.
Source Layer	Sourcelayer	The layer read from the second input.
[+]Layer Mode	Mode	How the second height field combines with the first where they overlap.
Blend	Blend	The mix between the first (0) and the second (1) field in Blend mode.
Base Scale	Basescale	Scales the first field before compositing.
Base Offset	Baseoffset	Offsets the first field before compositing, in world units.
Layer Scale	Layerscale	Scales the second field before compositing.
Layer Offset	Layeroffset	Offsets the second field before compositing, in world units.
Final Scale	Finalscale	Scales the result.
Final Offset	Finaloffset	Offsets the result, in world units.
Clamp Minimum	Clampmin	Clamps the result from below.
Minimum	Clampminvalue	The lowest result.
Clamp Maximum	Clampmax	Clamps the result from above.
Maximum	Clampmaxvalue	The highest result.
Do Falloff	Dofalloff	Weight the effect on each point by the Falloff Attribute.
Falloff Attribute	Falloffattr	The point attribute, 0 to 1, that weights the effect.
Invert Falloff	Invertfalloff	Uses one minus the falloff attribute.
Falloff Strength	Falloffstrength	Scales the effect of the falloff attribute.
[+]Border	Border	Determines how samples outside the height field are read at its edges. Streak repeats the edge value, Constant uses Border Value, Repeat wraps around.
Border Value	Bordervalue	The height read outside the height field when Border is Constant.

PAGECommon

Bypass	Bypass	Pass through the first input to the output unchanged.
Free Extra GPU Memory	Freeextragpumem	Free memory that has accumulated when output memory has grown and shrunk.
