I have seen the same behavior, where the water reflection seems to "turn off"(?) under a certain view angle, it looked like it could maybe be depending on the sun's position.

The video is a bit short to be sure, but perhaps it is related to this?

RE: Mayby bug in water
Reflections have not fully supported all material techniques as demonstrated in the examples below ... maybe this is a similar case where water does not reflect other water.

Tree with Leaf technique (shader) applied. Foliage clearly reflected:

   

Same tree with Test Blend Light Leaf technique (shader) applied. Foliage not reflected:

Haven't checked, but this could be due to the default value for reflection renderer type set to RT_SIMPLE (Can be controlled from the 'WaterClass' class, you can also enable shadows and more lights there)

--edit:
@link from yvanvds: Interesting info from Greg about the way water reflections are handled in the engine. I wish information like that would be gathered somewhere in the docs, instead of being scattered across the forums...

Thanks Para, that's a really useful piece of information. I'd not noticed that before. I'll give it a try and report back on the result.

Still getting the same results with the following setting:

Code:
Water.reflectionRenderer(RT_DEFERRED);

Yeah, that's fairly important information that again I was not previously aware of!

Thans for this info! I'll try to reproduce it while taking this in consideration.
