Flamingo Render Problem

[bylindsey]

I'm a new operator to CG but have commissioned many works before. I produced satisfactory results for a few days, but opened up the file today and Flamingo will only render the image in the flat default grey. In Rhino Render all the materials appear correctly. Clearly there is some default setting I've screwed up with in Flamingo. Does anyone know what this is?
