A bump just to keep this thread alive, and i do have a new update.

Yes, sid's house in the skybox, but the only problem i have is that making a 3D skybox for the map is going to be a very, very difficult task, not only to texture everything, but to be able to make it look good, too.
And obviously, i'm uncomfortable with this.
I was thinking about using Pixar's old way of getting around this, which is to draw a "skybox" for it, for an example, look at this official toy story short, and look outside the window.
