Method

This node shades particles using values generated by a fractal noise function, similar to the Fractal Noise Generator node but in 3D. The noise function may be sampled by the position of the particle in 3D, or the life of the particle.

Example

Transform

Name Description
Position X Position x in local space
Position Y Position y in local space
Position Z Position z in local space
Rotation Heading Rotation around y axis in local space
Rotation Pitch Rotation around x axis in local space
Rotation Bank Rotation around z axis in local space
Scale X Scale along the x axis in local space
Scale Y Scale along the y axis in local space
Scale Z Scale along the z axis in local space

Inherit Transform Channels

Toggle which transform channels should be inherited. By default, all are on.

Attributes

Name Description
Num Octaves How many time the noise generation is iterated.
Noise Scale Scale the size of any noise generated.
Animaton Rate The speed at which the noise is animated.
Lacunarity How large the gaps between the generated noise is.
Gain The smoothness of the generated noise.
Intensity Scale Scales the intensity of the resulting noise values.
Input Channel Choose how the noise affects the particles.
  • Position, 3D noise is generated and applied to particles based on their position in the scene.
  • Life, noise is generated based on the particles life.
  • Life With Random Offset, noise is generated based on the particle life, but is offset based on the particles position.
Radius Outer radius for which the particles will no longer be coloured.
Inner Radius Inner radius for which the particles will be coloured at their max.
Falloff Power How quickly the gradient changes from the inner radius to the outer radius.
Colour Change the colour of the particles as they spawn.
Blend Mode Choose how the particle colours blend to the source colours
Blend Amount Control how much the shader affects the particles.
