This article contains a list of known issues related to Corona and volumetric simulation plugins, and suggested solutions and workarounds. This includes:
V-Ray
Phoenix FD
PhoenixFD/VRayVolumeGrid in Isosurface rendering mode is currently not supported.
Phoenix FD Foam rendering is not supported in Corona 5 and older.
Fume FX
Corona currently ignores illumination map settings of FumeFX nodes.
Corona currently ignores motion blur settings of FumeFx nodes.
Corona currently does not support FumeFX with Space Warps.
Corona currently only supports rendering of FumeFX nodes using the Standard shader.
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
