Morning folks.  After a disasterous night of attempting to download Worldbuilder XT from DAZ (it timed out all my download attempts but one) I put together this test image.  I love Worldbuilder, think it's cool and it will eventually show up in much of my work, but can someone explain why it looks like everything is infected with pox or covered in ash?

Using DAZStudio 4.5Pro, plenty of RAM, on a new(ish) computer.
