heterogeneous volumes SkyLight VolScatter Intensity not working

heterogeneous volumes SkyLight VolScatter Intensity not working

Description

Heterogeneous Volumes do not respect the Volumetric Scattering Intensity values when running with Lumen, but do (correctly) when rendering with the Path Tracer.

Steps to Reproduce
  1. Download the attached test project and open
  2. Observe the Heterogeneous Volume “HeterogeneousVolume”, and it’s indirect lighting
  3. On the SkyLight, change the Volumetric Scattering Intensity between 0.2 and 1.0
  4. Observe no change to the Heterogeneous Volume (incorrect)
  5. Switch from “Lit” to “Path Tracing”
  6. Repeat step 3
  7. Observe the changes to the Heterogeneous Volume (correct)
