Hi...
I've thrown a quick test scene together to test the parallaxing with the perspective camera.
I've also used temporary images - I know the quality is rough, antialiasing etc. and blurry, but my main concern is that the Z index is very twitchey and parts of the scenery flash on and off or appear in the wrong order.
I can't find any setup of the perspective camera, only the short video on YouTube. All the info seems to centre around an orthograhic camera.
I've posted a webplayer to illustrate this. If you run the little guy the right the scenery appears, and then starts flickering and misaligning.
