Hi,

Could anyone help me with VDB noises and let me know what did I do wrong here.
When I'm applying Unified noise, or any other Volume VOP noise it seems like it is not affected evenly.
The left image shows what effect I'm looking to get out
The right image shows what I'm getting out.
Seems like all noises are affected like that.


1. In Sops, I have converted geometry to VDB Surface
2. Convert VDB surface to SDF Fog
3. Added VDB ACtivate to expand Volume
4. VolumeVOP added Unified Aligator noise
5. Converting VDB Fog to SDF
6. Convert VDB to Polygons

Here is the Volume Vop node graph:


In this Image, I have applied noise just to X-axis by using
VectortoFloat to preview how the noise is applied. Seems like the noise is being projected straight through the X-axis.
Is there a way to get the noise going from the centre?


I might have done something wrong here or not completed enough

Thank you for any help provided

Have you tried fitting the noise to go between -1 to 1 before you multiply by 4?

Sadly no, it did not helped in that case, but I found it useful in controlling the noise strength. Thank you
