Progress report
My 3D scene is coming together here. There's still obviously quite a bit more to be modeled, including one more room I want to make, as well as a bit of an outdoors area, and perhaps a shed or something.
The core concept is coming together though. The player can bring up their tablet with the puzzles they need to solve, while they are also looking around the scene for much-needed information about the puzzles.

One strange thing I need to fix--the fridge is not supposed to be pink (and there's a couple other colors that are also wrong). Somehow the UV's or textures must have gotten screwed up.
