Lighting

Shades particles based on the area of effect from lights.

Method #

This node shades particles based on scene lighting. The lighting calculation is an approximation based on the particle’s distance to the light and its facing direction, which is determined by either the particle’s normal if available or the orientation of the camera, giving a specular-like result. The Facing Direction Amount parameter controls the weighting of the facing direction effect so it can be blended out, leaving only the attenuation distance to generate the lighting effect.

Shadows cast between particles are not calculated by this node. To calculate shadows from particles use either the Volume Shadow Shading or Voxel Cone Shading nodes.

Parameters

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.

ParameterDetails
Position XPosition x in local space
Position YPosition y in local space
Position ZPosition z in local space
Rotation HeadingRotation around y axis in local space
Rotation PitchRotation around x axis in local space
Rotation BankRotation around z axis in local space
Scale XScale along the x axis in local space
Scale YScale along the y axis in local space
Scale ZScale along the z axis in local space

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

ParameterDetails
Position XToggle inheritance of the X Position from the parent.
Position YToggle inheritance of the Y Position from the parent.
Position ZToggle inheritance of the Z Position from the parent.
Rotation HeadingToggle inheritance of the Rotation Heading from the parent.
Rotation PitchToggle inheritance of the Rotation Pitch from the parent.
Rotation BankToggle inheritance of the Rotation Bank from the parent.
Scale XToggle inheritance of the X Scale from the parent.
Scale YToggle inheritance of the Y Scale from the parent.
Scale ZToggle inheritance of the Z Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails
Facing Direction AmountWeighting of the facing direction calculation as part of the lighting effect.
Facing Angle RangeThe angle range of the facing direction calculation: larger values produce a softer result.
Blend ModeChoose how the particle colours blend to the source colours
Blend AmountControl how much the new shading affects the particles.
