Hi Forum,
Long time Corona-user here (Version 10, Hotfix1). My question is if anyone else has been experiencing super-long rendering times when adding bitmap roughness to glass? Typical case would be a wine bottle-- adding in a tri-planar map for smudges, scratches..etc to the roughness slot. I am not sure if it's just me, but adding this in has dramatically increased render times (like 10x)... seems like much more than before. I am at the point that I have to abandon adding in details to shots.
Is there something in that workflow that is causing this very dramatic slow-down? Thank you!
