I am currently trying to finish my animation demo reel and I have encountered a few rendering problems. In my scene it seems like whenever I enable motionblur, some (or all) of the frames I try to render will be black with what appears to be some reflections still visible. My other problem is that motionblur also makes the glow effects act up; one frame will be fine and the next will not. I can do with scrapping the glow effects, but I really can’t deal with frames rendering completely black… I am not doing any kind of fancy rendering stuff, just using global illumination, basic lights, basic textures, etc.. I have also transferred everything onto my laptop which has a fresh install of Softimage 2012 on it, and the exact same frames will render black on there too.
Here are some screenshots to help describe what I am talking about, hopefully someone can help me out in any way possible. Thanks!
