This tutorial discusses many aspects of setting up an interior architectural scene for rendering. This includes: adjusting materials to use fresnel reflections (including proper energy balance); using multiple raydiosity bounces; adjusting raydiosity amplifier; raydiosity samples and cache settings; adjusting render Detail settings (Pixel Detail Block Size, etc.); Adaptive Shadow Sampling; custom surface controls; and more. NOTE: This is a bit of a longer tutorial so have patience :-)
