Default Lighting

Hi Guys,

I started a new project and setup what I would like to see as a basic game in TXB.

One thing I notice off the bat is it seems that the scene is being lighten strangely. Like there is a light in the middle of the screen... getting dimmer at the edges.

I really don't want that look. I want the lighting to just be based on the color of the tiles. Nothing more.

Where can I set this?

Thanks!
