Hi!

I have come across a problem when it comes to the edges of my hexagon world. Sometimes in some angels the edges/sides of the hexagons will show/shine through. Se picture below.

The hexagon mesh has 2 materials. One for the top and one for the sides. Where the top is Lit, opaque and the sides are none lit and opaque. Both of these materials are setup to not cast shadow but shadows can be cast on them.

Here is a quick look on how the world is set up. Is there any solution how to get rid of this lines? Its strange that if i change the lighting direction they sometimes disappear and appear in other angels/camera height.
