ProbeSet Dependencies tab

Probe set dependencies control whether or not light transfers between probe sets and systems. By default, all system dependencies are automatically calculated during the CalculateProbeSetSystemDependencies stage of the precompute. Setting up probe set dependencies can significantly reduce light transport time during the precompute.

If the loaded scene has at least one probe set, you can set the probe set dependencies on the ProbeSet Dependencies tab. When you click on this tab, the "selected" probe set is shown in yellow and the automatically-calculated systems on which it depends are highlighted in green.

Revert dependencies

Revert to the dependencies initially loaded with the scene.

Save dependencies

Save dependencies to disk. These dependencies are used for the next precompute of the scene.

Include all

Set all dependencies of the selected probe set to Include. Included systems are highlighted in blue.

Global include all

Set all dependencies of all probe sets to Include.

Auto all

Set all dependencies of the selected probe set to Auto. Auto included systems are highlighted in green.

Global auto all

Set all dependencies of all probe sets to Auto.

Exclude all

Set all dependencies of the selected probe set to Exclude. Excluded systems are not highlighted.

Global exclude all

Set all dependencies of all probe sets to Exclude.

Calculate dependencies

Calculate dependencies using the precompute API.

Load calculated deps

Load the calculated dependencies information (to allow changing the visibility requirement).

Selected probeset

Use the slider to select a probe set, if your scene contains more than one.

There are three available edit modes, controlled by the radio button.

Manual edit

Add or remove a dependency by right-clicking on the dependency and selecting from the context menu.

Radius cutoff

Enable the Radius cutoff controls:

  • The Radius cutoff slider allows you to set the radius cutoff for the selected probe set. All systems within this radius become dependencies of the selected probeset.
  • Click Apply radius to all probe sets to define dependencies for all probe sets based on the *Radius cutoff.

Calculated

Enable the Calculate and Load calculated deps buttons, and show the Radius cutoff and Visibility cutoff sliders that control the inputs to the precompute API function.

Make sure to save the dependencies before precomputing the scene.
