bunker Posted September 12, 2020 Share Posted September 12, 2020 I attached a simple example you'll need to write the volume to disk so Mantra can sample it at render time. volumesample.hiplc Quote Link to comment Share on other sites More sharing options...
Follyx Posted September 16, 2020 Author Share Posted September 16, 2020 (edited) 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. Edited September 16, 2020 by Follyx Quote Link to comment Share on other sites More sharing options...
bunker Posted September 16, 2020 Share Posted September 16, 2020 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. Quote Link to comment Share on other sites More sharing options...
