Ligthmass building suddenly takes forever.

For some reason now, on preview lighting it takes over a minute to collect photons and almost an hour or so to process the maps. There have been no changes to any important settings other than updating to 4.7 preview 5. Sure I’m using a lot of diffuse bounces, but it haven’t been this bad in a long time with the same settings. Is there something weird going on with 4.7 preview 5?

Hey fanzypantz -

Are you still experiencing this time increase in the current preview, 7? If so, can you please give me a description of what type and amount of items are in your level which cause this build issue?

Thank You
