Thanks for clarification. Now that I'm past the simpler aspects of workflow, I desire a bit of payoff
am rendering an animation for the next 11 days (so it appears). You've kindly reworked the stereo rig, if I'm correct - in response to my comments following my initial test on the stereo settings. I'm eager to repeat my test, and now that I've learned my way around a little, I can devise a better subject for the stereo testing, squaring the camera to the front face of Amazing Box, watching what happens in the far corners. I'll report back when I carve the time to do so, in the meanwhile, I humbly suggest changing the default stereo settings to a less aggressive 3D template. I've set my default, as you suggested, but others less familiar with stereo settings might benefit from a "safe" default setting. My definition of "safe"; since the camera is flying all about with subject matter constantly moving past frame edges, forward projected objects, while okay in the center of the screen, make for bad screen violations, or frustum clipping, so I set my Nearest Distance value equal to Screen Distance. A value slightly under the Screen Distance would allow for some forward projection, while lessening the edge violation. As for Screen Distance and Image Width, the default values of 2 and 1 result in such aggressive parralax, I have to work at placing my head just right looking at my Zalman in an effort to accomodate the entire image, the farthest point in the scene together with the nearest. I can do it, but it's a strain to do so, and others (less exposure to 3d, weaker eyes) had to work even longer or gave up, it hurting their eyes that much. Assuming no screen-related problems, i.e. crosstalk from angle of view exceeding the monitor's abilities, the double image seen is sign of the brain giving up trying to wrestle the two images into a unified stereoscopic whole. After much fiddling, I'm using 3.8 and 3.8 for Screen Distance and Image Distance, and yes, 3.8 for Minimum Distance. That's a comfortable 3D template.
I'm aware how religious many get about their magic 3D, I so hope not to come off like that. Just sharing, in the event you've spent less time on this aspect of your amazing work and value another's POV. Again, big thanks.
