In UGX Script Placer 2.0, you can choose the:

1. Main menu screen
2. Load screen
3. Mission screen.

I have tried to put images but it always tells me that for example: "Main menu screen is not a valid 2D material"

Is it because of the size, or does it need to be a different file type (if so how do I change my image to that file type).

Thanks to anyone who replies!
