Hi, When I try to merge 2 vdb's, octane only render the first one.
It work in mantra or Redshift but not octane. Is it a bug ?
I cannot combine them using a vdb combine cause i need them to have differents resolution.
Any help ?

Can you attach a scene to reproduce this problem here? I think that the main problem was that you need to define a group for each volume before merging them because without the groups the plugin can't know what grid must be used for each volume due to the fact that they have the same name (for example, two or more "density" grids in the same object)

No need for debug scene. I was indeed merging volumes without grouping them before.
Thank for the tip.
After creating a primitive group for each volume, octane can render the merge properly.
