What The Heck Is Going On?

What the heck is this?

I cannot figure out for the life of me what is going on here.

Here's what I have:
Fake stones (not important).
Planet 1 (the land).
Planet 2 (the water/ocean/sea).

Nothing else really, the shaders are real simple, Base Colors, and a sandy sorta color with an altitude height control, nothing special.

I have attached a couple of pics, one with the water plant rendered, on without.

I can't figure out if that is a shadow and I can't seem to make the water look right either, the sand is not smooth, don't know how to fix that.

I also can't figure out how to make mountains rise up on my land parts, I tried mapping an alpine shader with my continent shader, didn't work.

Any tips, ideas?

Share your TGD, though I don't have access right now.  Anyway, letting us see your node structure can sometimes fix things like this immediately.  It's likely something isn't connected correctly.

The dark area is a shadow from the water, because the water planet casts shadows. No other light is cast below the surface (except for GI), so this becomes a fully-opaque shadow. The reason it doesn't reach all the way to the shoreline is due to inaccuracies between the shadow-casting surfaces and the visible rendered surfaces.

The solution to this is to use a sphere, not a planet, for your water planet, because the sphere has an option to disable shadows. It can be given the same centre and radius values as planet.

Hey thanks, I'll try that.
