Weird stripes and stuff in Iray render

Okay, I just loaded one of the preset buildings (oddly enough, only reachable via Poser Formats) in Maclean's Room Creator Exteriors and did an Iray render of it.  On this one section of wall, I'm getting these weird white stripes and a dark triangle.  Any idea what's going on here?  0o

    Looks like the UV is screwed up. 

  • It's a known issue in Iray due to the overlapping geometry needed to provide the different options - the basic fix is to use the Geometry Editor to remove the unneeded mesh, though I can't help feeling it should be possible to do soemthing with displacement to move the invisible surfaces out of the way.
