I have and rfa porsche from this website. I import it into my project but when I render the porsche is all white, even the windows and lights. I open up the family file and whenever I click on it it is in a blue outlined cube. I tried to explode it but it says it cannot because it is a 3d object. How do I render this? Thanks

Go to your 'materials' tab and you will find a couple of new materials besides the normal materials that come from the family that you imported.These will often have names with prefixes like accurender//...These are usually set to render as white, go through these one by one and asign new materials and the car rendering should work fine.
