Hi @mwestphal,  
I found the issue in my other post ([Unpredictable behavior of paraview-lite - ParaView Support - ParaView](https://discourse.paraview.org/t/unpredictable-behavior-of-paraview-lite/13067)) is actually due to this boundary missing of VDB reader.  
And it cannot be solved by the `RessampleToImage`, since I want to apply contouring on the source.

Is there a way to modify the VDB reader directly? Thank you!
