This node composites the height field layers in the first ("base") input with the layers in the second ("layer") input. The third input takes an optional mask.
The node will properly composite volumes that aren’t axis aligned (it will use the grid of the base input). So you can position and rotate the composited volume in 3D space before compositing.
How to composite the layers.
The amount to blend the second layer with the first layer, when Layer mode is "blend". A value of
0 uses the first layer, a value of
1 uses the second layer, a value of
0.5 blends equally between the two layers.
A space-separated list of the layers to composite together from each input. For example,
height mask will composite the
height layers from each input, and the
mask layers from each input. The default is
*, meaning composite all layers.
If you use a mask input, the node only composites in the masked areas, and leaves the first input untouched in other areas.
If a mask volume is wired into this node’s second input, this specifies which volume in the second input to use to mask this node’s effect, usually
mask. Click the "Add mask paint" button to paint the mask directly in the viewport (this automatically adds a paint node to the second input).
Scales the values in the mask. You can use this to make the mask stronger or weaker only in this node.
Inverts the mask in this node, so compositing only happens in unmasked areas, and leaves the first input untouched in masked areas.
Add this to the values in the first input before compositing.
Multiply the values in the first input by this before compositing.
Add this to the values in the second input before compositing.
Layer Scale: Multiply the compositing layer voxel values by a given value.
Final Offset: Increase or decrease the final composited layer.
Final Scale: Multiply the final composited layer’s voxel values by a given value.
Clamp Minimum: Minimum clamped values.
Clamp Maximum: Maximum clamped values.
