Who? Oh, you must mean Hrnchamd.
Scripts can't be attached to statics. A shader solution on the other hand might be possible, but that would require MGE.
Yes, I stated that in the post.
Scripts can't be attached to statics I know, but they can be attached to activators, which work the same way as statics in most aspects, just with advantages. But if we're talking rain and weather here, they aren't statics, the meshes are hardcoded into the game, really limiting the options for weather customization.
On the weather topic, Hrmchamd, how hard would it be to make an http://i25.tinypic.com/2l8dx1g.jpg possible?
Another suggestion, make it so that plugins/master files can be dependant on plugin files the same way they can be dependant on masters, it would be really useful, and solve a lot of mod issues out there.
