Made a hall, that renders fine in Poser4. But when I render in Firefly, I get these strange patterns on the wall. Settings are: Production Quality, Raytracing, Shadows, Polygons, Texture Filter. Pixel Sampling = 3, Filter = 1. I used 12 spotlights in this scene. This pattern does not come from the bump map. Could it be caused by the light settings, shadows or anything else. Input much appreciated! Thanks - Walter
