Honor McMillian found a glitch in one of her photos. It has to do with how the viewer renders reflections of mesh objects. Bounce over to her site and see: Redefining Avatar in Second Life.
Notice the ship’s reflection. One must include avatars in the reflection settings to get mesh items to show a reflection.
I would call that a bug.
Honor points out another problem she ran into while shooting pictures. That particular problem is the reason that photographers use viewers with the Derender feature. The feature allows you to right-click an object and select ‘Derender’. It then disappears from the scene. Unfortunately the SL Viewers do not have the feature. Firestorm does… if I remember correctly.
