As to reference to the previous comment. Hami1810, could I ask how you might implement the same toggle for the "Water4" scripts? They are quite different from the Single script used by regular "Water (pro)" asset and I am not experienced enough to even begin to think of how to implement the same conditions for the other script.

Hi, based on the hints from this post:
http://forum.unity3d.com/threads/unity-4-3-1-occlusion-culling-and-water-4-reflection-issue.214028/
i put an new attribute to the the standard waterscript for toggling WaterOcclusion on and off:
you can download it here:

The only things you have to do, is to replace the basic Water-Script on the Pro-Water with the water-occlusion script.
If you dont see any changes in your water, start the game.
A disadvantage is, that you increase your drawcalls by turning the water-occlusion off.

Just checked and the refection camera has OC turned on by default ... so no idea what to do :(

Yeah, this is happening to me with Culling & Mirrors (Realtime reflections).
The mirror shows virtually nothing since all object have been occluded from it?

Hmm, maybe there's a way to set that camera to use OC as well? :O

This is still occurring with 4.3, any suggestions?
