Chris: Was your large project imported to 3DS from a .dxf file? I've had most of the problems you have described with geometry created in a CADD package and then imported. You could mess around with welding vertices but you may try the opposite approach if you have rectilinear geometry – Detach Faces. I had faces flickering and these strange fading triangular voids which all became normal when I detached the faces (Your dark stripe may be similar to this). This leads me to believe that my problems were in the smoothing groups assigned and/or the weld threshold used during import. Detaching the faces was the fastest way to an answer but perhaps not the most elegant or efficient for rendering. Bob

>>stripe, window to corner… I hope you have this fixed by now, but here's my 2 cents… My latest encounter with window/wall stripes was just today. <g> In my experience, this is almost always caused by a thin sliver of a face. These used to cause me a lot of grief, but I can usually fix them in about 30 sec. now. Look at the ends of "edge" of the face carefully and make sure the edge is not actually more than one face. Sometimes a boolean will leave very thin faces that confuse the smoothing algorithms. Try Select/Face/Single or Mod/Vertex/Move (watch the rubber-band lines) to track down a rogue face. Also, increasing the weld threshold, then selecting all the vertices in the area and welding "Selected" should zap any errant face slivers. Also, if you've done any manual vertex editing on the wall, you may have inadvertently "folded" a face over another, resulting in a discontinuity. In this case, the Edge/Turn command can usually repair the object. JKJ
