petipet's Sci-fi UFO in Iray

jjoyner

I purchased petipet's Sci-fi UFO yesterday and installed it (DIM) today.  When loaded into the viewport (DS 4.15), the top, sides and underside of the UFO display in the viewport in Texture Shaded preview mode regardless of the material (Iray or 3Delight) applied.   However, when in NVIDIA Iray preview mode, only the top and sides of the UFO display in the viewport; if I angle the UFO so that the underside should be displayed, the UFO vanishes.  I have attached a series of screen captures in three file formats.  I pretty much have the default setting applied in the Render pane, Draw pane, etc. don't have any unusual settings applied.  Can anyone point me to what is causing the problem?

Is Draw Ground on (Render Settings)? If the camera is below ground level, anything above the ground disappears.

That did it.  I knew it would be somethong simple to fix but would be difficult to find/know about.

Thanks much.
