A game to test an idea, prerendered point and click

So this is the first time I've built a game like this. It's a pressure cooker style horror/escape room game. 

But I wanted to make sure it looked amazing, and the unity engine doesn't do real time rendering justice. 

So I decided to work with Blender to make some stills that the game basically uses as most of its visuals. By doing so I was able to take advantage of the lighting that fully rendered images from Blender provides...

Look how clean that is. 

To ensure that I lined up the camera with the objects, I then brought the model into Unity along with the default Blender camera so I could line things up. I deleted everything except for the display screen. I then gave that object a render texture.

Off camera, I set up another camera with a canvas that renders onto the surface of the screen with the material set to cutout. The result looks like this...

The buttons are actually another canvas in the world space which is set up to match the surface of the desk before it was "removed" from the scene. Since everything is already in line with the original camera, it looks like it is part of the flat image behind it.

Later. I wanted some motion, in things, so I rendered animations out of blender and made movies of those which I brought into unity. Again, these play out and it appears as if everything is live in Unity, but it's not. 

I'm not going to share those scenes here, as I don't want to spoil the game for anyone. It is a horror game, after all.
