I'm creating a stage scene for my project for university but have a few problems.

- I have a massive Tv screen in the scene and when I first started the project the screen and the video playing on it was quite bright and looked great on the renders but now for some reason its not bright or that visible anymore and looks quite dark. How do I change that? I tried doing the self immunation but that doesn't seem to work.

- Another problem was the flooring, it's meant to be reflective and I used matte/shadow/reflection on it and turned on recieve reflections and fiddled with the settings for the floor to look glossy and pretty reflective but for some reason when I drag the material over to the model, it goes on the entire scene and not just the floor? Someone said to me that I needed to change the number in the material's window to 1 and so fourth? But I have no clue lol.

Could anyone help?
Thanks
