Hi there, this is an old issue that we are aware of and have it logged.
(Internal ID=910407615)

The workaround is to ensure the bounding box does not intersect with other objects.

Hi, I came across the same issue. I'd appreciate if you could fix that soon. In the current state it would require a lot of postproduction to make it usable, in some scenarios.
Nevertheless, possibilty of a cooperation between C4D Pyro system and Corona is great!

Best,
Lukasz

Hey there,

I've found it seems to be linked to IOR of the intersecting material - may be a fix here somewhere

Corona 9 Hot fix 1  come out. And this bug still here  .
Why you dont fix this bug  so long time ?  It was in  Corona 8 and may bee  before  8 .

In most cases  its  not  usable . Because  vdb object is in the middle of  bounding box. And I need to put it close to the ground  or  wall .
