Radar Waterline adds configurable underwater restrictions to Create: Radars. Submerged antennas stop scanning and normal radar no longer detects fully submerged targets by default, giving sonar a proper role beneath the surface.
Features
- Submerged antennas stop scanning. Normal radar cannot acquire or update contacts while its antenna receiver is underwater
- Underwater targets require sonar. Fully submerged entities and supported Sable vessels are hidden from normal radar, even when the radar is above water
- Raised radar masts work. The addon checks the assembled antenna receiver rather than its bearing, allowing a submerged vessel to operate an exposed radar mast
- Surface ships remain detectable. Target checks use vessel bounds rather than just their center
- Sonar stays unaffected. Echo Radars can continue sharing underwater contacts through existing radar networks, monitors and weapon systems
- Dry submerged cabins are covered. A configurable overhead-water check prevents radar from working inside enclosed underwater air pockets
Supports moving and rotating Create/Sable contraptions. Echo Radars, Sable and Create: Deep Seas are optional. Keep Create: Radars installed- Radar Waterline is a separate addon.
