User Manual

When using Displace 3D, keep in mind that it only displaces existing vertices and does not
subdivide surfaces to increase detail. To obtain a more detailed displacement, increase the
subdivision amount for the geometry that is being displaced. Note that the pixels in the
displacement image may contain negative values.
TIP: Passing a particle system through a Displace 3D node disables the Always Face
Camera option set in the pEmitter. Particles are not treated as point-like objects; each
of the four particle vertices are individually displaced, which may or may not be the
preferred outcome.
Inputs
The following two inputs appear on the Displace 3D node in the Node Editor:
–
SceneInput: The orange scene input is the required input for the Displace 3D node.
You use this input to connect another node that creates or contains a 3D scene or
object.
–
Input: This green input is used to connect a 2D image that is used to displace the
object connected to the Scene input. If no image is provided, this node effectively
passes the scene straight through to its output. So, although not technically a
required input, there isn’t much use for adding this node unless you connect this
input correctly.
Basic Node Setup
The output of a Displace 3D node typically connects to a Merge 3D node, integrating it into a
larger scene. The 3D geometry you want to displace is connected to the orange input, and in
this example, a Fast Noise node is used to displace the geometry.
