I don't think Q2 had any rain textures.
Edit: And if you've done rain the way I think you have, the r_speeds may not be bad, but it will rape the fillrate on lowend cards.
aren't we breaking copyright law with your jitdownload funcs by downloading these textures off servers
The download functions currently used are the Quake2 ones. I never finished my fast file downloading implementation. Regardless of the method used, transferring copyrighted material to somebody who doesn't own rights to use them is illegal. It doesn't matter if you transfer them through the game, a web browser, bittorrent, or kazaa. The game engine is open source. The game media is not. Also, the textures use a different palette and look awful in paintball2 anyway. If you want to use Quake2 stuff, use it with Quake2.
