I mean, if you were really dedicated, you could probably drill a hole in a piece of wood with a screwdriver rather than a power drill if you wanted, but why would you?
You are probably better off just using the right tool for the job
If you are presenting a live gameplay demonstration, maybe that would be useful, but even then I’d probably just prerecord some screepcapped video.
I’ve given live gameplay demonstrations in the past, and something I’ve discovered is if theres an embarassing bug that you haven’t found yet, it will rear it’s ugly head during your live demonstration, usually at the WORST possible time. If not, you’ll forget how to do something, or something else will happen, something always goes wrong.
I mean, it’s E3 week, so what better time to remember the Sony Wonderbook moment. It’s something that happens every year during Sony’s E3 press conference, where they have at least one segement go ridiculously wrong, and it’s usually a product no one cares about anyway, like the Wonderbook. It’s just something that is bound to happen.
You are probably better off pre-recording the segements you want to do in Unity and putting them into your Powerpoint or whatever equivilant you want to use.
Though, if you could somehow use Unity to make a VR Powerpoint style presentation that everyone could bust out VR goggles for, that would be dope. I’ve seen 3D videos on Youtube that were kinda like that.
Of course, this is probably impractical for your purposes, so I’d probably stick to powerpoint.
