Does UE5 Support Ray Tracing The Ocean System?

Lumen working fine. Scene consists of rock meshes surrounding a landscape. The Lake Water system has been added to the landscape. However, I don’t seem to be getting the mesh rocks tracing into the Lake Water system.

I then created a test shot with a landscape and Lake System and placed a textures sphere just above the water surface. I see no reflection of the sphere into the water surface.

Is this a limitation of the Water System?
