Roland Z. said: I'd be happy with just a color customizable Fog of War - I'm going to be running Reign of Winter soon, and was looking for vision obscured not only by darkness, but also by swirling snow, fog, rain, whatever. But an image would be even better! I love the idea of blueprints superimposed over the actual map. You might want to look into the API script "Page FX". It can be used to simulate swirling snow, fog, and rain in a given area around a token on the GM layer. As the script description says; " This script allows GMs to set up environmental special effects for their maps by producing customizable, randomly distributed fx over some area. This can be used to produce various sorts of atmospheric effects like rain, geysers, steam, bubbling magma, sparks, etc ."
