Can I ask how you are getting the reflections to work?
With r.VXGI.SpecularTracingEnable disabled, I get screenspace reflections - but that only works for high gloss surfaces.
With r.VXGI.SpecularTracingEnable on, I find that reflective surfaces will only reflect direct light:

All attempts to use reflection captures or environment maps with specular tracing just gave me completely black reflections…

Hmmm, not sure why that is happening. comment from one of the engineers might be relevant: “we compute VXGI Specular Tracing only for pixels that contain a specular material.”
