prop_physics don't lit up

Hey, got a prob again, when I place prop_physics in my map they are all black ingame:

But when I shoot them a few times so they move they will lit up how they should. There are no leaks in my map. Can anyone tell me what’s going on? Cheers!

I really hope someone know’s how to fix this otherwise i can just throw my map away :frowning:

I fixed it, i had all my lights have the same name but they didn’t have any input or output. Just removed the names and it’s fixed!
