Can't lit the background

johranshadi

The background of this pool is dark. Although i put all type of lights behind the pool but nothing seems to lit the background. I used cube and pannels to create the pool. This is so frustrating. Any suggestions?

So what is behind the pool?

If you doesn't put nothing behind the pool you can't choose nothing!
Use a plane to make a background or use the "Environment" tab to choose an image or a color.
