I'm a newbie, but learning quickly.  I'm working on Cararra 8 Pro on Mac Snow Leopard platform.  I can get the sample render in the assembly room to render beautiful skies, but the main render room only renders all skies as bright white.  This is with no change of camera position.  I've tried multiple types of skies and multiple settings in the render room, but the sky is always white.  Have I missed something, or is this a program bug?  Mark your C7Pro tutorial DVD set was great!  Thanks, Greg
