4.26 water components don't render

I managed to make the Ocean water work but other components aren’t working properly

  • Lakes and rivers: don’t render at all
  • Custom water body: renders the surface, but not the underwater post process.

It’s supposed to sculpt the landscape as you move the component but it’s not doing anything.

It seems the lake is rendered under the landscape at the same height than the ocean, any idea why is that?
