1. load Room_02.iprop from the iRay/Light Studio props. 2. render with iray "Render Scene", option "iClone Render", looks good, just like "Iray preview render" 3. render with iray "Render Scene", option "Standalone Render", part missing in corner of room
See attached image.
As best I can tell it is not a near/far clip plane issue. It's something about the geometry in the corner of the prop.
