Additional issues

Volumetric effects may not render as expected (may disappear completely, produce artifacts, or cause excessive noise or other unwanted issues) if:

• The camera is placed inside the medium (e.g. inside a Phoenix FD object, or inside a mesh with CoronaVolumeMtl applied)
  
  
• A light or object with CoronaLightMtl is placed inside the medium
