Occlusion States

• fast outline
• soft outline
• wide outline
• surface fill

Using the Render setting of an outline, it can be configured to render in 3 ways.

1. Always: Always render the outline/fill, regardless of its occlusion state in the scene.
2. When Not Occluded: Only render the outline/fill when it is not occluded (not hidden behind other geometry).
3. When Occluded: Only render the outline/fill when it is occluded (hidden behind other geometry).

The 3 occlusion states are shown below.
