Problem with reflections

Hello,

Hello,
I’m currently in the middle of the corridor tutorial by WoLD. I’ve spotted it somewhere around 5th hour of working.
The problem is that the floor material wont reflect the emissive meshes anymore. It was ok but now it’s gone. I’ve even tried to open new projects, reimporting meshes etc but nothing helps.

And now this effect is gone.

Thanks

Ok, found the problem. It was Engine Scalability setting.
