Where are reflection data stored?

A technical question. Where are the data baked from Sphere/Cube reflection stored?

Our project setup is fully dynamic lighting , DFAO with LPV.
I understand technically these are for static lighting only , but reflection capture seems to work perfectly for us.
However we have a quite unique setup for lighting. we tend to store our lighting in sublevels so they can switched in the beginning of level. However we’re encountering issue where we do not know if the reflection data is updated. At this juncture I have 2 questions :

  1. is it recommended to move reflection actor to the lighting sublevel? are the data stored there? it is currently in the master level.
  2. is there a way to trigger recapturing during runtime . I’ve read about a console command which is able to do it but was removed. Any ideas?
