    • NodeGraph / Right Mouse Click / Add Nodes / Layer / Extension Pack /




The Height Blend Node allows you to blend together two Height/Displacement or Bump maps. It is capable of outputting either

the combined new Height or a Mix Mask that you can use to blend entire materials.

Node Overview


Node Ports


  • Height (BG)

The Height Map for the Bottom Layer


  • Height (FG)

The Height Map for the Top Layer


  • Mask (optional)

Exclude areas from being affected by the FG Height.


  • Offset

Applies an Offset to the Top Layer Height Map. Overwrites the Height Offset Slider of the Node


  • Contrast

Determines the contrast of the Blending Mask generated between Top and Bottom Layer. Overwrites the Contrast Slider of the Node



  • OUTPUT Blended Height

A combined Height Map from the Bottom and Top Layer


  • OUTPUT Mask

A Mask how the Bottom and Top Layer have been combined that can be used for Material Blending



Node Properties


MAIN TAB


  • Height Offset

Applies an Offset to the Top Layer Height Map


  • Contrast

Determines the contrast of the Blending Mask generated between Top and Bottom Layer


  • Mode

Determines the algorithm used to combine the two height maps


    • Balanced Height


Will constantly re balance the two height maps to achieve a realistic result


    • BG Priority


The BG Height will remain unchanged and the FG Height is 'moved' through it.


  • FG Opacity

Applies a simple Opacity to the Mask used to blend the FG Height over the BG Height, meaning the mask will

get more weight added uniformly



  • Mask Weight

You can use a Mask attached to the Mask (optional) Nodeport to exclude areas from

being affected by the FG Height.

The Mask Weight affects the attached Mask or acts against a value of 1.0 if no Mask is attached.


When the Mask Weight is 1.0 or lower it multiplies against the attached Mask or 1.0 if no Mask is attached

When the Mask Weight is larger than one it adds a value to the Mask making the Mask go overall more towards a constant

value of 1.0
