The water in this image had (and still has slightly) the old problem of lines appearing on the surface. What happened to the option of  micro-vertex jittering? I thought that was intended for use in such scenes. I managed to reduce it by moving the center of the lake away from 0,x,0. to 500,x,0.
Comments welcome.

great atmo!

I really don't see the problem...to me the water is very nice.

Look to the right of the sun just below the horizon, about a third the way over between sun and edge of pic.

I haven't done a water render yet, but it seems more pronounced on the terrain than it used to be. Maybe it's just me................

What happened to the option of  micro-vertex jittering?

This has moved to the Render Subdiv Settings node, which is in the render node's internal network.

I'd never have noticed that...does it happen with zero waves/flat surface?

Great image. A truly lovely deep palette in a tranquil scene, very enjoyable!

[DocCharly65]

Very nice!

I don't see the water problem too.
But it could be interesting to see the scene with almost no waves and some quite intensive wind patches. What do you think?

Ah! Very well hidden. It's only visible though via the Node Network window and not from viewing the internal nodes of the Render window. 3 of the internal nodes are there, but not he Render subdiv settings.


Anyway since it appears that micro-vertex jittering is on by default, it's still not getting rid of these lines.


Thanks for the positive comments though!


Here's a worse case clip:

No, only when  waves/roughness enabled.

I know that artifact. What if you use a sphere for the water? Never tested that. It might even have to do with the 256 boundary of seeds, so every 256 'ticks' the same pattern is repeated. So, perhaps mix 2 water shaders, or 2 PF's for waves? Also never tested that, so just thinking aloud.

Then try tweaking the displacement tolerance in your Lake in it's Surface shader as it's Default of 0.5 isn't much
