Prevent Displacement Offset Anomalies

[WAS]

So I have some cool embossed snow I found here (forgot from who). It looks pretty decent at a distance. But I notice when trying to add it to my volcano scene I am fiddling with (to learn clouds) it causes the clouds to offset as well through the visual plain you are looking from.



Is there a way to isolate clouds from the rest of the scene so they are not effected?

I seem to recall some issue like this that resulted from particular settings in Intersect Underlying (in the Surface Layer settings). Try disabling that if it's enabled and see if that fixes it. If so there may be some way to adjust the settings and preserve most of your snow surface while avoiding the sky issue.

I could also be completely wrong.

I seem to remember that too, pretty clearly actually.
Somewhat more vaguely I seem to remember it should also be fixed or behave better in these circumstances.

Well this was caused by favor depressions, which is sad cause it does kill the look of the mountains snow without it. I wonder if isolated to the atmosphere to a hidden second planet may be able to resolve it.



From what I see that did fix it. There seems to be other issues with the displacement on lateral though, maybe cause of how extreme it is at displacement 5 (I do see some stretched shelving from extreme displacement)

But I am now wondering why light is showing through the solid rock, and reflecting in patches of snow down the slope face. I removed translucency from the snow, thinking that was it, but to no avail.

In your first image, it looks like the displacement could be creating some very stretched micropolygons. If you don't use "defer atmo/cloud", then each micropolygon is given a single colour including the cloud colour, so the cloud looks like it's stretched along with the terrain.

It might be a bug with Intersect Underlying but it's hard to tell. It might just be shape of the terrain and the renderer doing what it does when deferred atmo/cloud is turned off.
