Well, that's strange. Not sure how I got the wrong file, I used the links in the OP... oh well. I tried the file you found for me (thanks, btw!) and changed my forge to 518 and this time, when I enable the shader, I don't get any more blackness... however, I also don't get shaders either. It just looks like normal minecraft.I'm testing this from my work computer, which might be different, but it's got a decent video card and I would think it would work just fine. It's an nVidia GT 620. I'll try again when I get home, maybe it'll work on my main computer. Will report back if it worked or not then.Edit: I found one that works! http://www.mediafire.com/?9jm2v2gfddxwdgp This file, combined with the forge 518 makes beautiful shaders that crush my puny work computer's framerate to dust. I'll have to try this at home where my main machine can handle the awesomeness.
