The actual shadows are fine, but the hard shadows at the banks are, well hard. Is this the terrain reflecting and just being really dark?

That's a reflection of the terrain. I think N-drju was talking about the shadow of the sun.

From what I can see in his "Solved" example, it is the hard reflection. His hard reflection is more aligning with the actual shadow though in his example. And both my examples, and his, Standard handles this refleciton better.

Sorry for coming back late to this topic but...

Yes, I meant the shadow cast by the sun and light transmission in particulate medium.

I actually see nothing wrong with reflections being hard - it is natural I'd say and accurate in TG. After all, reflections in stagnating waters can sometimes be as sharp as in a mirror, right?

In that case something in your render settings is breaking the shadow calculation, or shader itself. Cause PT shadows are fine in any situation I test. You can see the shadow transmission through the sediment fine.

Hmmm, strange.

Maybe it is a shader, who knows? Could you share an example from one of your trials? I'll be happy to compare once I finish rendering my NWDA.

I uploaded the original TGD to this topic few posts back.

Indeed. Looks like I have "detached" myself from this topic after a while. ;)
