If you've imported the brick shape and it's correct, the issue is probably whether you've used uv mapping to apply the texture to the object. Check out the faq on the Zaxwerks site for more tips on importing 3D objects from other apps.
Yes, apparently UV mapping was an issue for us.
Since my post, we have tried using Maya instead of Cinema 4D.
As of this post, we are still working out the kinks - but we're optimistic that changing programs and utilizing UV mapping will give us better results.
