no, it was HSVTM=1.67, gain =1.33, envdome/hdri and one inf lite at 75%, 4 IDL bounces (quickie).

it's gonna look too dark to many, as this sponza building is like an elevator shaft - even with 16 bounces there ain't much to reflect, excepting the floor.  it would look better in something bright with alotta sky, e.g. the free OBL compound and envdome.  or I could put some lites in the sponza atrium.
