How to avoid the artefact in the following picture

[PeterParker]

Hello,

does anybody know this little issue? Dont know how to avoid the lines in the Mountain. It´s not in every place but here and there.

That is a hole or some kind of severe vertical displacement. It's either an artifact in the Alpine Shader (are you using Terragen 2? not sure if it was ever fixed before TG3), or you're using some kind of harsh mask or something. Posting a TGD would be helpful.

Thanks for your answer Ohyan
I use Terragen 3 Prof.+Animation when i use the Alpine Shader alone this also occurs. I´ve used and Alpine Project i think this was from NWDA and makes good
usage and the rendering is also fine. Here is the File for you:

It looks like that one particular seed of the Alpine Fractal produces a fractal with that broken area. Just testing by changing the seed up one or down one number and I can't see visible problems in the area. Also I see the camera is somewhat far from the 0,0 point. I wonder if the "bad" peak being located 24 Kilometers east and 20 Kilometers south from the origin 0,0  point might be a contributing factor ?

This happens to me all the time when i use the Alpine Shader. It´s not on every Mountain but looks terrible. Havent fix the problem yet. I hope Oshyan will fix it up

Yes, it's in the alpine fractal, just a bad number. But there's something in the Green Vally node that I'm not too happy about either; fuzzy zone of zero, bound to produce trouble.

We did fix some issue related to this previously, but it appears there may still be some. It might be only when there is more than 1 lead-in octave though, so you could look at that setting and see if adjusting it helps.

Isn't it, like, that stichable border is turned off or at 0 value? That would give vertical cut for sure.

Just sayin'.

[Oshyan]

Stitchable Border is a Heightfield node setting. The Alpine Fractal is a procedural shader node, not a heightfield function.

Thanks so far Oshyan but what do you mean with 1 lead in octave?

[Oshyan]

There is a setting in the Alpine Shader called "Lead-in Octaves". It defaults to 0. If yours is higher than 1, that may be the source of the problem.
