At the pictures you see the same light on different models. If i create a ship one of this three colors is there... this color is there the compülete time the ship is ingame. i can save/load the game and the color is the same... Jumping in an other sector also has no effect.

This problem i can watch at every ships with positioning lights and every color. For example with the color green there are minimal differences but they are there.

Currently i can exclude nearly everything.
I tried using some other shaders than effects.fx (engines.fx, standardlightning... ). With this shaders the color was like it should be but the "black" part of the texture was to see.

Another try was to use the shader-properties of a bullet (for example bullet_GaussCannon) and change the shader there to standardlightning.
The effect was this:
