I'm facing a problem when rendering any pair of equirectangular images from inside a 3D modelling package (Maya in my case, but no doubt the same issues apply to many different packages). The attached (side-by-side format) image is an example. I'm hoping the good folk on this forum can help.
I render out my panorama (I use the Lat-Lon Mental Ray lens plug-in) and it looks as you'd expect. Looking at it through the excellent VRPlayer, it works well. I then shift my camera to another position approx 6.5 'virtual' cm to the side of the first position and re-render. Again this panorama works fine on its own.
I was hoping that I could just place these x2 renders side-by-side (as they are in the attached example) to make a 3D version of the scene. Not so. What's happening is that the 'forward' view works fine but the depth gets reversed towards the peripheries of the image (which just looks bad) until the 'back' view is completely inverse (and so look pretty much OK again).
Logically I can see that the reason is that the 'Right camera' becomes the 'Left camera' as it renders the part of the view directly behind itself. However, I haven't got a clue how to fix it and output an equirectangular panorama that works in 3D. Help!
