How to fade out edgy polygons facing away from camera?

How can i make planes ,like the one marked red in the picture, fade out?
And i am not talking about occlusion culling, i just want faces which normals are angles too hard away from the cam to fade out.
Let’s assume i use the opacity to fade it out.

Using the Angle between camera and normal works only correct, if the camera rotates around the object’s center point.
The picture displays the issue: all the marked faces have the same normal, but only the middle one should be culled.

Any ideas?

You need to use direction vector from camera to pixel instead.

Well, that was my mistake, i was using “CameraDirectionVector” instead of “CameraVector”, thanks alot :slight_smile:
