pancho simpson Posted January 17, 2005 Share Posted January 17, 2005 hi, i just posted in the general A:M forum but it seems i can´t post images there. Well here´s the render i mentioned w/ my makeshift area light. I think it looks alright but there are artifacts that bother me a bit, in the form of weird shadows in the forehead. However, i believe it´s the lighting since the model has already been smoothed out w/ porcelain and it´s articfact-less w/ the default chor lights. Any thoughts?

Bruce Del Porte Posted January 17, 2005 Share Posted January 17, 2005 Can you post a wireframe, are there splines running along those shadows? Quote Link to comment Share on other sites More sharing options...
pancho simpson Posted January 17, 2005 Author Share Posted January 17, 2005 actually, there aren´t splines there and the wires can be found @ http://www.hash.com/forums/index.php?showtopic=10374&hl=semi the forehead hasn´t changed althougt the cheeks have!

jesshmusic Posted January 23, 2005 Share Posted January 23, 2005 I'm not an expert, but the problem may be the z-buffered shadows. Can you get better results with ray tracing? I also noticed that the interior of the head is lit, but I can't remember how to fix that. Ha! I guess I didn't help too much! Quote Link to comment Share on other sites More sharing options...
pancho simpson Posted January 25, 2005 Author Share Posted January 25, 2005 I also noticed that the interior of the head is lit, but I can't remember how to fix that. i think that's the direction of the klieg light. Anyway, ray-traced shadows look very grainy even at 10 ray cast Quote Link to comment Share on other sites More sharing options...
jesshmusic Posted January 25, 2005 Share Posted January 25, 2005 Have you checked out Yves's Lighting Tut? This may help you a lot. http://www.hash.com/forums/index.php?showtopic=10132 Quote Link to comment Share on other sites More sharing options...
pancho simpson Posted January 28, 2005 Author Share Posted January 28, 2005 hmm, thanks but i´m trying to stay away from radiosity and the huge rendertimes (i have an 800MHz celeron!). Quote Link to comment Share on other sites More sharing options...
