I'm creating a small solar system where i would like to show the dark and the bright side of the the earth. My problem is that when i see the earth from behind, to show the dark side, there appears a light around the edges (first picture, only in eevee). But i would like to see it just all dark. If i put down specular in the light settings to 0, i get the desired result (second picture) but then i miss the reflection on the earth.
I tried it with a spot, sun and a point lamp. with the point lamp it works, but it does not work for the whole project. The problem appears with a sun and also a spot lamp.
Does anyone know how to solve this?
Thanks for the detailed information. Unfortunately it didnt solve the problem. I opened a complete new blend file with a new uv sphere, no materials added at all. and there i got the same effect, but only if the light is in a certain distance from the uv sphere.
