Caustics Volume

How to place caustics.

Caustics may be positioned using caustics volumes. These volumes are cubes that may be translated, rotated and scaled. Caustics will show up wherever the volume intersects with existing scene geometry.

To help you, the caustics volume shows debug lines of the wireframe of the volume. The lines are shown in white where they intersect with existing scene geometry.

The debug view may be hidden using the Display Debug Overlay toggle in the script inspector.
