How do you make your tori look like it has shiny joints, kinda like they're wet or glass sorta? My shader's don't do that...Do I need a different version of toribash to make it do that?

And also, I have three toribash folders, one for each version ( I updated it two times ). But it doesn't let me delete the outdated folders and it's taking up space. What do I do with them to get rid of them?
