Another question from henners. According to the acad2004/viz references, logarithmic exposure control is useful in conjunction with radiosity. Exterior daylight option should be checked if the scene is outdoor. It also says that Logarithmic exposure control is great for animations. However, what if I want to create a walkthru from outdoor to in? Checking Exterior daylight option renders interior too dark. Unchecking it renders exterior too bright? Thanx Henry
