Water doesn't appear when playing in editor

Hi,

I have a water volume that you can see in the images while editing, but when I click play to test this out, the water is hidden, it’s definitely created in the level because I checked the Outliner during play and even entered the volume which started a post process effect, I’m just not sure why the surface doesn’t appear?

During editing

During play

Furthermore, if I play the game, click the water volume from the Outliner and unclick Render CustomDepth Pass it appears as it should, if I disable it, it doesn’t change, but this can only happen if I edit its setting during gameplay?

This water system is an experimental feature at the moment and I haven’t been able to work out why it sometimes just isn’t visible despite being loaded into the world successfully.

I’ve instead just created a Cube shape and added the Water_FarMesh material to it to simulate the same thing or at least very close to which seems to work to the same quality.
