Hi,
you need to have the same Volume step length in order to avoid seams with overlapping volumes.

The only solution is to lower significantly the volume step length,
sadly this also increase render time proportionally.

Hello,
today I've come across this problem and spent some time to solve it, but I couldn't.
Is there any explanation about this issue?
