If you're using Soft Reflections with the Reflection Shader, then the problem is probably too low samples or too high softness. It needs very low values. Glass shader, Reflection shader, and Water shader all work similarly, and render similarly. You're not going to fix such issues by switching; if it's fixed, it's probably because a feature is no longer being used because it's not available in the other shader (e.g. soft reflections).

It may have been the samples. I had it set to 6; default is 4. The softness of the reflective shader was 0.1. Maybe 0.04 would be better.

Thanks for the advice Oshyan.

As you can see from Martin's advice here, the softness values should actually be *very* small, perhaps even smaller than 0.04:

And 6 samples is really not much with a softness at 0.1. You'd need more like 16-32 to get decent quality there I think. Not that it's necessarily worth it. But if you use smaller (much smaller) values you can use fewer samples.

I used 0.002 (!) and 4 samples in the latest River, which works fine.

Well I think the Glass shader worked just fine. Got rid of a lot of noise. I was aboot t suggest dialing back the reflection on the water shader myself but what do I know....heh heh heh....Love this image btw.
