Glossy material rendering black, in a scene with environment and emission lighting Having a bit of an issue, just messing around with some game models. And whenever I apply a glossy shader it renders black, just for the car/tires model (pre modeled). Any other objects (newly created) render the glossy just fine. I have a plane with an emission shader as well in the scene.

Thanks!

EDIT: .blend file
Deactivate autosmooth in data tab and it will be ok.
