Issue with ZBrush 4r2

[Permafrost]

I am having an issue with the latest version of ZBrush. Whenever I load in my mesh it is showing up pretty much as a silhouette. This happened when I was using spotlight. The turn in for my uni. assignment is monday evening, and I still have a lot of work to do. Here is an image of what it looks like, I need a quick fix for this and using a previous version isn't an option at this point as I have done a few days worth of work on this bust, but if that is the only option for me I have no choice, just looks like i'll be pulling an all nighter.

Maybe your F6 button is stuck (which switches automatically to Flat color), or If you're not using a flat material make sure Render > flat isn't on.

i had similar problems. it solved easy , i just export model to obj , and then reimport

Nope F6 isn't stuck and Render > Flat isn't turned on. I have no clue what is going on right now.

@ geck Thanks that worked. That is very weird there, not sure what happened. Thanks a lot though, much appreciated.
