Hi Kim, I wrote PrecipitationEffect for a driving simulator quite a few years back. The scales of the bricks used in the rendering is tailored to what works well for town scenes and driving speeds. The scales doesn't work well for high speeds and large landscapes that you'll have with a flight simulator.
It should be possible to adapt to work with the large scales but the techniques used would probably be stretched too far and would no longer be visually compelling. For a flight simulator speeds and scales it would probably be best to come up with alternative implementations. It might be that you could provide a consistent interface but just change the back end implementation for the different scales. Robert.
