Facing
Updated: 9 Sep 2025
Generate a gradient from the direction a surface is facing.
Facing
Method #
This node generates a gradient for a shading system, using the angle between the surface normal and a direction either generated from the node’s rotation, or a target position in the scene.
The output of this node is a shader, which can either be combined with other Shading nodes for more complex designs, or applied to Materials to directly control one of the material channels. They can also be applied to Fields, where they can be used on the various channels on the Field Emitters to control how the smoke is generated, and Field Materials to control how the field is rendered.
Parameters
Parameter Details Position X
The shader’s position along the local x-axis.
Position Y
The shader’s position along the local y-axis.
Position Z
The shader’s position along the local z-axis.
Rotation Heading
The shader’s rotation around the local y-axis.
Rotation Pitch
The shader’s rotation around the local x-axis.
Rotation Bank
The shader’s rotation around the local z-axis.
Scale X
The shader’s scale along the local x-axis.
Scale Y
The shader’s scale along the local y-axis.
Scale Z
The shader’s scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Position
Toggle inheritance of the Position from the parent.
Rotation
Toggle inheritance of the Rotation from the parent.
Scale
Toggle inheritance of the Scale from the parent.
World Position Only
Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time
Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details Mapping Type
The input position channel.
- World Position : The shader is generated in world space.
- Object Local Position : The shader is generated relative to the object.
- Texture Coordinate : The shader is generated in UV space, and mapped using the object’s UV’s.
Mode
Determines how the direction value should be calculated.
- Direction : Uses the node’s rotation to determine the direction value.
- Target Point : Uses the vector between the node’s position and the node’s position to determine the direction value.
Invert
Inverts the facing result.
Range Min
Controls the lower value of the output range.
Range Max
Controls the upper value of the output range.
Power
Controls the power curve between the high and low values.
Preview In Viewport
Passes this node’s output to the destination material as a colour channel, so it can be previewed more easily.
