Probe Lighting

Method

Creates dynamic reflections of other objects in the scene, by rendering them from specific points within the scene.

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.

Note that the materials that should show the reflection need to have its Reflections property enabled.

Example

Here the teapot is reflecting the coloured and textured walls via the Probe Lighting node.

Transform

Name Description
Position X Move its position along the x-axis in local space.
Position Y Move its position along the y-axis in local space.
Position Z Move its position along the z-axis in local space.
Rotation Heading Rotate the object about the x-axis.
Rotation Pitch Rotate the object about the y-axis.
Rotation Bank Rotate the object about the z-axis.
Scale X Scale along the x-axis.
Scale Y Scale along the y-axis.
Scale Z Scale along the z-axis.

Inherit Transform Channels

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

Attributes

Name Description
Brightness The brightness of the reflections.
Map Size The size of the generated probe reflection image in pixels, for each probe.
Num Renders Per Frame The 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.
Dynamic When 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 Probes Show 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 Radius When probes are being shown, this property can be used to set their radius.

Inputs

Name Description Typical Node Input
Affected Objects Choose which nodes are affected by the light node. by default, all are affected. 3D Object
Point Cache An optional point cache to use when generating the probe images. Point Cache

Outputs

All nodes connected to this node are treated as if flowing to the parent node, and inherits any transformation changes along the chain.
