What size should screen overlay image be?

Sorry if I posted this in the wrong forum…

Ok,

so using the standard unity start up default settings and pro version of unity, I would like to add a camera overlay image. Now what would be the correct size to create this image in photoshop?

Depends on the resolution of your target system, but if the overlay can be blurred e.g. a splatter effect then you can probably go for a fraction of the full size.

If your going for PC/Mac check out the steam stats, and if it’s webplayer check out the Unity Webplayer stats for resolutions.

Thanks for the reply!

I am targeting PC so I will have a look.
