Some of us have water bases or islands and the problem we face is when we shoot down the heli the loot boxes sink to the bottom and are hard to find or the sharks kill us before we get to the boxes.

We would like to have a plug-in where the loot boxes float to the top as they do when you retrieve the boxes attached to sunken ships but without going underwater

There is Floating Items but it doesn't seem to work with heli crates. The plugin adds Buoyancy to configured items, but heli crates are not referrable via item ids. I didn't find any other plugin providing similar functionality.

The OnEntitySpawned hook gives access to those crates with the corresponding prefabId but applying Buoyancy to them has no effect. Maybe there is another way to do it.
