Probe Lighting

Probe Lighting

Use connected probes for lighting.



Method #

Creates dynamic reflections and lighting of a scene by rendering low-res sphereical captures of the scene (probes) and using their renders as a source for specular reflections and diffuse lighting.

A Point Cache may optionally be used to allow the reflection images to be generated more efficiently when there are a large number of probes to process. this can improve performance, at the cost of quality.

Materials that should show the reflection need to have Probe Lighting Reflections property enabled in their properties.

This nodes output can be connected to the Probe Grid node to generate a grid of points to draw from, or use Nulls to specify capture positions for the probes.


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.

Position XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.

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

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.

BrightnessThe brightness of the reflections.
Map SizeThe size of the generated probe reflection image in pixels, for each probe.
Num Renders Per FrameThe number of probes to process each frame, allowing a full update to be spread across multiple frames so that each individual frame can render in less time.
DynamicWhen this is set on, the probes are continuously re-generated. When it is set off then the last-generated probe set is used. Setting this off can improve performance.
Show ProbesShow the probe images that have been generated as textured spheres.
  • None : No probes are shown
  • Diffuse : Diffuse reflection images are shown
  • Specular : Specular reflection images are shown
Probe Display RadiusWhen probes are being shown, this property can be used to set their radius.
