How about using plain old textured plane crosses for clouds at bigger distances? (the way trees are done, only with a (or several) horizontal plane(s) added) These might work better for bigger structures like cumulonimbus, and such, too, as you can control the shape a bit. (no fancy shader

Yes, certainly. I suggest that we pack your /Models/Weather/ then into a tarball and I host that for the time being as a dds texture patch to Local Weather so that people can test what works better for them. Once we know how this affects different systems, we can decide what to do and which
