heightField node

This node draws a plane that shows the displacement of a surface texture or an ocean shader.

It is currently only for preview purposes, and does not appear in a render.

Attributes (8)

cacheNeedsRebuilding, color, colorB, colorG, colorR, displacement, heightScale, resolution

Long name (short name) Type Default Flags

cacheNeedsRebuilding (cnr) bool true

A convenience attribute that forces all the inputs to be updated

color (cl) float3

Color is the basic color of the preview surface. This may be mapped with a surface texture or an ocean shader. The mapping will always use the outColor from the connected node, regardless of the actual attribute connected.

colorR (cr) float 0.5

color red value

colorG (cg) float 0.5

color green value

colorB (cb) float 0.5

color blue value

displacement (dis) float 0.0

The height of the plane. This may be mapped with a surface texture or an ocean shader. The mapping will always use the outAlpha from the connected node, regardless of the actual attribute connected. This does a special fast evaluation of the texture that will ignores added shading engine inputs.

heightScale (hc) float 1.0

Scale factor for input displacement.

resolution (res) integer 10

The number of samples relative to the largest side of the plane. For a square plane the ocean will be sampled at resolution * resolution points. Higher values result in a more detailed surface, but slower draw time.
