Hi Vel, I'm not so sure about your question about backdrop libraries. I'm not at all familiar with World Builder. If you mean to ask if you can use a bitmap image for an atmosphere, then the answer is no. But if you're talking about a background image, yes, you can--- you would simply have to map it to a plane and have it fill up the background. THe link above is to E-on Software, the makers of Vue, where you can find out much about the program, and also download a limited 30 day demo. The demo actually is pretty good. System requirements are about the same for any graphics app these days, but Vue currently is Windows only: 95/98/NT I have 128 MB RAM and a 600 mhz Athlon, on Windows 98 SE and Vue runs great with that setup. Many people use much less and get great results. :) I hope this answers your question well enough. :) --Mike
