Hello,

While playing with Noise I noticed these artifacts that appear. My noise is relatively simple in terms of its values. These artifacts follow the noise translation operations.
You will find in the same file a Base illustrating this same problem with TOPs.
My graphics card is an NVIDIA RTX 4080 Super with a driver version: 561.09.
Thanks!
Just for our reference - there is a post dealing with the same issue in TOPs.
Also this one might be related.. so it’s something that’s there for a while.
It says resolved, but I dont think it is completely.. My intuition says it has something to do with the pseudo random number generator for the 3d & 4d simplex noise. 2D simplex doesn’t seem to have any issues.
Cheers,

Just did a quick test with 2023.12000 on windows & 4090 and can confirm it’s still there.

It seems that the line goes through the origin with a 45 degrees angle. When resizing the image to 1024x256, it looks like this:
Hope this helps.

Indeed but if, on this 1024x256p noise, you translate the noise to [ 5.07 ; -0.01 ; 0 ] you can see another type of shape. It’s very strange.
It’s very annoying in my case because I’m trying to create like a video game. So the noise is translating when the player moves to create mountains, etc. So there are some translations areas that are okay but some where the player meet these lines and then goes under the map 
Indeed, the use of 2D types noises resolves this problem. I hope that it gonna be fixed for 3D and 4D noises 
Have a good day !
