Can't see buildings?!

Hey, I’m pretty new to Unity, this is actually only my second time using it, and I’m having some problems. So I was using this tutorial: http://workshops.ko-opmode.com/

and as you can see I used Google Sketchup to the models. Nothing fancy just simple little cubes and polygons. I also used the first person drifter by Ben Espsito for my camera. Now I’m not sure if this is a Unity problem or a sketchup problem or what, but for certain buildings when I look up I can’t see them. I also can’t see them from a distance. If I’m not directly in front of it I can’t see it. I can only see one of the buildings from all angles, the rest just kinda phase in and out depending on what I’m looking at them from.

When I look at the game from the “scene” screen I can see all the buildings just fine, the problem start when I play the game. I’ll post a link to a video from another version I did Saturday with the same problems so you can see what I’m talking about.

Thanks for the help.

(Yeah the camera is super low but I fixed that)

it’s cool, i figured it out.
