Intersecting VDB volumes possible?

[Stefan-L]

as title says, is this possible?

i sadly get weird artefacts if 2 or more intersect

Hi, unfortunately, this is not possible and also a known issue.

Hi Stefan, Are you able to share your example with us?

[Stefan-L]

yes i can share an example of course, but maybe it was a false alarm, - when i let it render longer, the visible intersecting bounding box erros i see at start pof the renderng, seem to resolve after some longer render time. so maybe it is ok, just needs longer:)

should it work in v8 ?
if yet i test it deeper with longer render times

Hi Stefan,

Disregard my initial reply. After speaking with the team, this should be working if let to render longer. If any artifacts are still visible you can try adjusting the Interpolation to ''Quadratic'' (which is slightly slower but gives better results) and playing around with the step size.
