Yep, made a thread a while back asking about cascading LPV, which is very similar to cascading shadows. Starting to wonder if they’re dependent on Lionhead for updates. I asked a couple devs at the Portland developer meetup that didn’t have answers either, which is understandable since they’re focused on only specific parts of the engine or specific projects.
Certainly not lacking in imagination for what I want to use LPVs for, surprising how quickly dead ends were encountered. No offense to the Epic team which are doing awesome work, but it made me sad that the only update to LPV in 4.3 was fixing a crash that didn’t exist in previous versions 
Any lighting solution that is dependent of stagnant static scenes is staying disabled whether I’m using LPV or not, unless of course I decide to abandon my project and make something that is just a twist on the same old rehashed formulas we’ve been seeing for years with only a minority of stand out exceptions.
