Volumetric Fog: Is Indirect Light Scatter Supported in Lumen?

Hi,

Using pre-rendered lighting (UE4) it was possible to have indirect lighting scatter through volumetric fog, as in the following image:

Is this possible in UE5 using Lumen?

The documentation seems to suggest it is possible:

Lumen also provides lower-quality global illumination for Lit Translucency and Volumetric Fog.

My attempts to recreate indirect scatter using Lumen have been unsuccessful however. I’m wondering if the feature really is supported, and if anyone has had any success with it?

Any insight on this would be much appreciated.
Thanks

Did you try to raise the indirect lighting multiplier in your light sources? Unfortunately doesn’t seem to work with 5.1 anymore.
