Dark areas appear on object when shaded
 

Hey, Im modelling an object in maya which has many sections that slot together to create a cube like object but seperate when needed.

I want thin creases running round the edges by slightly bevelling the edges and i have tried to do so but i get dark patches appearing when the object is rendered or shaded.

Is there a problem with my geometry?

Please take a look at the attached images.

Thanks,
Ben

Here's the wireframe.

And the render.

This might help...assuming that the geometry is ok.

select the object, then under normals menu, select soften edge. Then with the object still selected, open up the chanel editor. You will see the softedge in your history with an option to change the angle. Try an angle of 30 to begin with and if that doesn't work then just try different angles to see if you can find one that works. If not, then it's probably a problem with your geometry. If so, maybe do a clean up.

Thanks for your help Perfecto, i tried changing the angle but to get rid of the patches the other edges became too sharp so i just applied it to the edges around the seam and its improved a lot.

Thanks,
Ben
