I am working on a space scene using a 3D model of a starbase that I downloaded online. There's a sun in the scene that illuminates the starbase. The starbase gets illuminated in Cycles, but when I switch to Eevee, it does not receive any light from the sun.

Comparison

The node tree of one of the "head" of the mushroom-shaped starbase looks like this: Node tree

Am I missing something fundamental that you more seasoned pretzels can see at the first glance?

  • $\begingroup$ Have you tried to bake indirect light? Maybe placing a reflection cubemap around the spaceship? $\endgroup$

  • $\begingroup$ it should work, as the directional light is no material emission or primarily indirect. Maby its something else? Could you upload a file? $\endgroup$

    $\begingroup$ sry tried to take a look, but the file is pretty complicated (many small nested parts) and i dont have much time at the moment. What i found was that there are countless lamps inside the station. Also copying the hole station to a fresh blend-file brings the error along, copying single elements doesnt. Maby this way you could narrow it down, which object causes this behavior. $\endgroup$

I could narrow it down to the huge number of lights (134) in the scene. Deleting all lights and adding a fresh sun restores the display of shadows. By using the new filtering parameters, lights can easily be found:

It looks like that eevee cant handle that many lights and additional ones will simply be ignored: https://docs.blender.org/manual/en/latest/render/eevee/limitations.html
