The lights are the same on both models but it's not rendering the other one. Im trying to render in eevee. Here's the blend file https://drive.google.com/file/d/1hn9aGMnDRiOCK2LCi9MmTNJLzxkpdzAh/view?usp=sharing
You've hit the maximum lighting limit for Eevee.
The Blender manual here states that
- Only 128 active lights can be supported by Eevee in a scene.
- Only 8 Shadowed sun lights can be supported at the same time.
- As of now, lights can only have one colour and do not support light node trees.
I would suggest moving the duplicate ship over to a separate view layer, then combining the two using the compositor.
