I'm having trouble rendering a project, and I can't find any relevant threads in the community forum.
There is a light reflection that is appearing in the rendering with no apparent source. I hid all of the lamps, cleared all light sources, and covered the model with a plane — just in case it was "sun" shining through a crack. (I also checked to make sure all my walls actually join.) The reflection is still there.
Additionally, (possibly related?) my night time lighting renderings are coming out super bright. It looks right in the speed preview, but not in the final rendering. I tried messing with the settings of the lighting as well as the photo editor, but can't get it looking right. It looks right in the speed preview though! Gah!!
