I noticed I can output stereoscopic movie just by using ray-mmd/Extension/StereoImage, so I thought I'd give it a try.
Does anybody know how to adjust the parallax? Changing the parameters of Horizontal.x didn't seem to make any difference. I guess the function 'ComputeStereoCoord' in 'stereoscopic.fxsub' is doing some calculations and the argument 'maxSeparation' may be the key, but I've got no clue to where this function is called from.
