how do you deal with background comp

[leo_surrealismo]

I allways use direct visibility and refractions in black so I can comp the background in post without issues; but particulary in this scene is not totally working. I have a glass reflection in another glass and obviously, i gets a black refraction and partially coronasky.
Could anyone point me in the right direcion?  whay would be the proper workflow?

Sure, feel free to submit a new support ticket: https://support.chaos.com/hc/en-us/requests/new

Currently I can only recommend:
- enabling the black override for reflections, refractions, and direct visilibty
and/or
- using the "propagate" option in your materials: https://support.chaos.com/hc/en-us/articles/4528327507729-How-to-use-Masks-with-Reflection-Refraction
