I would like to check and see if anyone out there has experienced an annoying problem that has just cropped up on me en route to a deadline. If I can fix it today I can still save a couple of stills, but this problem will still be in most of an animation that I may not be able to redo in time. I have a curved surface (long arc) that represents a fascia with typ. material and mapping to represent stone. I created a second set of faces along the same curve but offset a couple of inches in front of the fascia object. The second set has all edges invisible except for the top and bottom edges. I applied a 2-sided, Phong, wireframe (1-pixel) material to the second set. The wireframe object should appear as a thin line on the fascia, which it had up until now. Part of the wireframe object is casting a shadow on the fascia surface, even though I have turned off the Cast Shadows and Receive Shadows buttons on the object! By moving the light source and rendering with/without shadows I have confirmed that the second line appearing is a shadow, but I cannot seem to get rid of it. It has created an ugly smear along the two edges on half of the fascia surface. The only other idea I had was to exclude the object from the spotlight, but that does not affect shadows. If anyone has any ideas I would greatly appreciate it – I'll be on the road some today but will check in as much as possible. In the meantime I'll go eat some more Tums for that lovely feeling in my stomach – the one I've seen many of you describe when some problem wrecks a lot of work! Thanks in advance…. Bob Keefer
