Over the course of few months I been rendering tons of textures, although these are mainly for the new explosions you can probably use them to tweak other things as well. Just rename the files to corresponding textures and you should be able to make new unique explosions. I have so many textures I couldn't possibly use all of them, and not only that but it takes long time to come up with the right combination of textures to make a nice explosion.
