I'm nearly sure that it has something to do with the "Perlin 3D scalar".
When I delete all of these P3D from my process, I have no more spike (see the new render).
Now I'm rendering another view where the landscape is based *only* on the Perlin 3D scalar, and the spikes come back.

So, what can I do now ?  :-\

Looks very good. This is a technique I have been wanting to explore, but do not have time for yet.

Test your inputs and settings to the Perlin 3D Scalar and see if it's being caused by extreme settings/inputs.

Thanks for narrowing it down. I don't think there's anything unusual with your setup. No further testing needed on your part. It's probably something I overlooked when making the Perlin node safe for multi-threading, or I incorrectly optimised something later. I'll fix it.

Just to add, I've been experiencing the same problem when using Perlin too.

I still got the problem with the new version (2.2)...  :-[

This topic was opened during last january and (considering the last answer from Matt) I thought where would be a fix for this problem... now I can see it was totally forgotten.

Yip, i get the same error. something is wrong with the perlin noise node. but well, you can use a power fractal instead.

I'm sorry about that. I'll make sure it's in the next update. We'll also have a much faster turnaround on the next update.

I think that's reasonable.

No more problem with the new version. Thank you very much !  :)

Now I can go on with the "dunes & sandwaves construction".
