Walls are blending over each other

Hi, i can’t really find the words for my problem, since english is not my first language.
But you can see my Problem very well on this screenshot: http://i.imgur.com/Z4W5XlY.png

I have cubes as walls, all with the same height. They are alligned to form an obstacle and when they are in game view, you can see that they are fading over each other, which makes ugly brigther spots (red circles).

I am using an perspective camera and a spotlight. Is there something i can change on the shader to make this stop??

Thanks!

Just position them well, use snapping, check out the docs. And here’s a tutorial.
With vertex snapping, you won’t have placement problems :slight_smile:

It is because the polygons overlap each other. Change little wall height to lets say 5.03, higher or smaller, or place boxes so there is a tiny gap. Otherwise, if can do the previous ones i mentioned, model the walls in 3d max or blender and then import it as one mesh.
