Hi again everyone, the image I have attached is a high quality render with global illumination etc. The objects are on a wall, and they are lights faciong up and down, with globes inside them set to around 600% strength, to make the walls light up nicely. I also have a blobe in the room set to around 70% to give some ambient light. I can't work out why I am getting those sections of light right behind and beside the lights' shadow on the wall. Its really irritating me. I want to just have a nice dark shadow there, but instead I am getting these yuk sections of light. How can I avoide this? I still want to use GI Rendering. Scott Richardson
