I am combining two VDB volumes and it looks like the smaller VDB bounding box region is showing through.
Any ideas what may be causing this?
Thanks

Hi Peter,
do you have different Step length values between the two?

Yeah same step values... I attached the packaged file to see if that helps pinpoint it.
I am guessing because the original VDB's are of different scale ... bu that is an uneducated guess : > )
Thanks man

Hi Peter,
here is my attempt: the two vdb files are differnt, one has the temperature grid while the other not.
I have changed the scale values to match the max values, I have also reduced the step leght at 0.4 and now the overlapping cube seems gone:
