I think this project is not compatible with Unity 6.

The Boat Attack project you opened is using a very old version of this repository, since it's using the old package name com.verasl.water-system

Try the rendergraph-U6 branch, which has been updated to support RenderGraph and should work better with Unity 6: https://github.com/Unity-Technologies/BoatAttack/tree/rendergraph-U6

The package is not compatible with Unity 6.3 LTS. There are too many compiler errors to list here.

@jamesarndt82 The BoatAttack repository has a branch containing a package that is compatible with Unity 6.3 LTS. https://github.com/Unity-Technologies/BoatAttack/tree/release/6000.3/Packages/com.verasl.water-system

It's based on the older 1.4.0-preview.1 version, so it's missing effects such as screen-space reflections.

Since the rendergraph-U6 branch of boat-attack-water still has issues in 6.3, such as gaps in the water mesh, I think the best approach is to modify the 2.0.0-preview.1 or 2.0.0-preview.2 versions of this repository to include the Rendergraph compatibility changes of the release/6000.3 branch of BoatAttack.
