I've been working on the primitive challenge for January (late, as usual) and have come up with something I rather like.  But every time I render it....whether it is in open GL, preview, Hybrid, etc., the final render pass turns everything black, obliterating everything....  I've played around with the render options, trying to find out if I've set something incorrectly, but don't seem to have.  I'm using Vue 7 Infinite...  This ever happen to anyone else?  What's going on?  It only happens with the primitive scene, no others.
Thank you for any input!  mcw1917
