Weird shading artifacts where two vdbs overlap

I'm on 19.5.303 and octane 2021.1.5.0.
I'm getting these (image attached) ugly artifacts on the edge of two volumes overlapping. Is there any way of getting rid of these?

It's usually resolved by setting the same step length for the rendered volumes.
Worth mentioning, from

Better overlapping volumes
You can increase the maximal amount of overlapping volumes to be ray marched to 16. And we improved rendering of small dense volumes inside large volumes which usually have very different step lengths.

Yep that was it. Once I changed the volume step length it went away! Thank you!
