Help. Last night, for some inane reason, I reset the default preferences of Carrara (it seemed like a good idea at the time, honest!). Now the shader folders that I had over time added have disappeared. A couple of years ago I had purchased the real world metal shaders from the renderosity store (the ones made by Litst)and now I cant even find the orginal files on my computer to put them back in the shaders tray. Is that normal? I can understand reseting the default preferences would return the shader tray to its original state, but it shoud not erase the shader files from my computer should it? Any suggestions?...please....anyone....I soooo love those metal shaders... H&B
