Gradient 3D [3GD]
The Gradient node
Gradient Node Overview
The Gradient 3D node is used to texture objects with a variety of gradient types. It offers many
of the same controls as the Background node. While it is not possible to transform the gradient
directly in 3D space, it is orientable using the following nodes:
 Texture Transform Node: The Texture Transform node can be used to adjust the
mapping per pixel.
 UV Map Node: The UV Map node can be used to adjust the mapping per vertex (use
the XYZtoUVW mode). This has onscreen controls, so you can see what the gradient is
doing. Using this node is recommended because it is faster to evaluate.
The gradient defaults to a linear gradient that goes from -1 to +1 along the Z-axis.
All primitives in the Shape 3D node can output a third texture coordinate for
UVW mapping.
Inputs
The Gradient node has no Inputs. The output of the node is connected to a material input on
3D geometry.
Basic Node Setup
The Gradient 3D node below is used to generate a resolution-independent 3D texture for an
FBX imported model. Positioning in UVW space is easiest to do using a UV Map tool placed
after the geometry.
