Display multiple scenes?

I have a game screen and when ‘pause’ is hit I’d like to pause the scene, keep it rendering in the background and bring in the new pause options to the forefront.

Was just wondering how to best go about doing this?

Well, with LoadLevelAdditively, you can load multiple scenes at the same time, but are you sure that’s what you want? If you just want some options and a menu, you can just use UnityGUI for that. Alternatively, you can have a ‘menu’ section of your scene which is on an exclusive layer so that it does not interfere with your main scene, and then activate a camera inside of that.
