RWC acts as the glue to SMP that tells SMP where to place clouds in a scene based on real world METAR data. Let's use the following example to explain it: We are going to assume RWC is NOT installed in the following example. 1. San Francisco, CA is reporting clear skies 2. Oakland, CA across the bay is reporting overcast 3. San Jose, CA on the south side of the bay is reporting scattered clouds   Let's say we fly from SFO-OAK-SJC for purposes of demonstration.
