The Portals package brings the Portals/Volumes/Tunnels feature to Crest 5. Portals restrict rendering of the water surface and volume to a mesh using either the front or back face. Volumes restricts rendering of the water surface and volume using both the front and back faces.

This feature can be useful for aquariums and underwater windows. The promotional video shows the volume feature and then the portal feature (inverted) respectively.

Tunnels can be used to efficiently remove water from an area, which enables tunneling under water level.
