Heightfield Distort

fields/heightfield-distort·v1.5.1

IN:1 OUT:1

SUMMARY

Heightfield Distort resamples a layer of a height field along a world-space noise flow, so features are pushed sideways along flow lines instead of up and down. Curl noise swirls the terrain without piling it up or thinning it out, while Simplex pushes it in and out.

Amplitude and Element Size are in world units, Octaves and Roughness add finer detail, and Substeps let large distortions follow the flow smoothly. Animate Offset Z to evolve the flow; the falloff limits the effect to selected areas, and Height or any other layer can be distorted.

PARAMETERS

PAGEDistort

Layer	Layer	The layer moved through the noise flow (Height warps the terrain sideways, a falloff layer warps the falloff).
[+]Noise Type	Noisetype	Curl gives swirls that neither pile up nor thin out the terrain; Simplex pushes it in and out.
Amplitude	Amplitude	How far the layer moves, in world units.
Element Size	Elementsize	The size of the noise features, in world units.
[+]Offset	Offset	Moves the noise in world units. Offset Z moves through the noise (animate it to evolve the flow).
Octaves	Octaves	Sets the number of layers of finer noise.
Roughness	Roughness	The strength of each finer octave relative to the previous one.
Substeps	Substeps	Splits the movement into steps that follow the flow; raise it with the Amplitude for smooth swirls.
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.
