Generate simple noise.
Noise
Method #
This node generates simple white noise, for use in a shading system.
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
These properties control the core behaviours of the node.
Parameter Details Mapping Type
How the generated shader is applied to the surface.
- 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.
Amount
How much noise is generated per pixel.
Intensity
The intensity of the effect that is applied.
Scale
Scale the size of any noise generated.
Preview In Viewport
Preview the effects of the shading node on the channel it’s applied, without other nodes further in the chain being used.
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
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.
Inputs
