Hey everyone,
I am currently trying to use geoemtry as a volume. I tried different things, but it is not wokring yet.
At the moment I am using a volume and then a volumevop with some noise in there. But the volume is always a box, but I would like to have a different shape. I know that I can use a “vdb from polygons” node, but this one doesn't seem to work with the volumevop node.
Could anyone give me a hint into the right direction? That would be very helpfull.
Have a nice day
Anna

Moin, Anna,
there is a difference between “volume” and “vdb”, that's probably why you got stuck. While a vdb actually “is a volume”, the benefits of VDB are, amongst others, that no data gets stored when there are no voxels, so you can safe a lot of memory footprint / bandwidth.
If you *want* to convert a VDB into a volume (loosing the benefits of vdb), you can use a
A “volume” (including a vdb) always is a box in its outer boundaries, because that is how the cell collection is set up (x/y/z), however the axis can have different sizes and so can the resolution/axis.
I hope this helps!

Good bye.
