I’m exploring lighting with cycles and can’t quite work out what’s happening here. A cube on a plane with a sun lamp gives sharp black shadow in BI, but almost no shadow at all in Cycles even with shadows checked in the Integrator and the world color set to black so as not to introduce ambient lighting. I’m wondering how one could ever represent a city scene this way.
Must have had some odd settings. Doesn’t look light I can get parallel light rays though.
