When you turn on stereoscopy, then you will find the menu item Set Stereo 3D in the Windows menu. Here you can find other methods to display the stereoscopic image. Interlaced for example. The viewport displays the result then.
You can find similar settings in the Output panel in the Properties editor. But when i change the method and render the image, then the result is still rendered as anaglyph. And not as interlaced.
How do i render an interlaced result instead of an anaglyph one? And what is this settings in the output panel good for then? They seem to do nothing.
Kind regards - Tiles
