I cant seem to get these caustics right. Enhanced High Antialiasing, and 6.5 hours of rendering, with every ray traced option available applied. Any Ideas?

Something weird is going on here, because the stem of the goblet is giving off some sort of illusion, like it's trying to be both an inside and outside surface. First thing I'd do is find a free goblet/wineglass object somewhere, then start playing with the surface properties until you get a glass surface you like. After that, then try the air surface/glass surface/air surface trick, which I take it is the ghost around the goblet. If I recall correctly, newtekniques had a good tutorial on glass, or try looking elsewhere on the web for LW specific glass tuts. Hope this helps...

not sure what all you did. After you lathed it, did you copy the object to a new layer, flip the polys, and then paste it back into the original layer? Something I saw at www.mgfx.net. Check the lw 6.5 tut there.
