Cloud: Overlapping Bounding Box

Hello, everyone,
I have a problem with the overlapping of the bounding box of VDB clouds.
I want to build a compact cloud front from single clouds in C4D using the cloner tool. Unfortunately there are big problems with the overlapping of the clouds (Boundig Box), see picture.
I tried a lot with the VDB settings - "Density", "Volume Step Length" but nothing worked.
Is there a solution or a workaround?
I'm looking forward to constructive answers - thank you!
Best regards, Udo

Hi,
this technique is not good, Volumes have issues when overlapped.
Better to create the volume composition you need in c4d R20/R21, and import back as vdb:

Wasn't this supposed to be fixed in 2019.2?

Hello, Beppe,
Thank you so much for your answer.
Yes, I know your technique, but I can't get the quality I get with "real" cloud VDBs.
By the way, Redschift has no problems with VDB - Bounding Box Overlay.

@KeWee, yes that would be nice if the problem was already solved.

When I use RedShift, everything works out fine.

As far as I can remember, Jules confirmed on FB a few months back it shouldn't be a problem with, I think, 2019.2 anymore...

Thank you for your comment. Unfortunately I am using version 2019.1.4 and the problem is still not solved.
Octane always had the problem, I hoped it would be solved now - unfortunately not yet.

Really frustrating... I didn't need it in my last projects but was certain it would be fixed. Here the statement from Jules:

Maybe a dev could say something on this?

I know I'm not helping, just wanna point out how Otoy communicated this problem.

Edit: one suggestion: you have to use the same step length on every VDB object. Lino even showed that it was fixed:

Have you tried turning off the " emulate old volume behaviour" in the Octane Kernels setting ( down the bottom) ? i find that helps for me.. (sometimes)

Thanks Raoul for your feedback, I have tried your tip but unfortunately it has only little effect on the problem.
