How do I efficiently render exteriors with Radiosity?
You can efficiently render exteriors with Radiosity by: 1. Using Custom Radiosity render mode, select the Include Visible Surfaces Only checkbox in the Radiosity Optimizations dialog box. This means that only the visible building facade will be involved with Radiosity processing. The objects and surfaces that are behind the facade will not be included in the Radiosity processing. 2. Set large ground planes and tree image props to not emit or receive, using either Edit Texture or Object Info palette radiosity overrides. 3. Set the Obj Inclusion slider in the Custom Radiosity Options dialog box such that only the largest lit surfaces will emit (grey), and the smaller details like window mullions and door knobs will only receive (red). 4. If any surfaces are not visible that do produce significant indirect lighting (like flat roof surfaces that aren’t visible in the current view), they can be forced to participate despite not being visible by setting either an Edit Texture or Object Info
