Hi ,
I assume you're referring to the Path Tracer. If so, then, unfortunately, these are current limitations of the Path Tracer, where certain elements aren't supported by the Path Tracer renderer. A full list of limitations of the Path Tracer are:
- Caustics
- Decals
- Weather height fog
- Volumetric light shafts
- Light haze
- Point clouds
- Flag animation
- Sun shape visibility
We hope to remove these limitations in the future.
Best,
Raghib
