I attached a simple example
you'll need to write the volume to disk so Mantra can sample it at render time.

Hi,

sorry for the late reply, was pretty busy. Unforutantely there is no output in your file. Cached the volume, but nothing as the red character in the rendered pic.

this is what I get in the mantra render, I even downloaded the file from the forum just in case.
check that the file : /tmp/volume.bgeo.sc exists on disk.
