I’m testing merged stereo panorama rendering in 4.0.2, and the options don’t appear to be behaving the way the documentation describes.
The headset I’m targeting wants 4k square images arranged top-bottom.
Camera:
- Stereoscopy Mode: Off-axis
- Spherical Stereo: On
Output:
- Resolution: 4096x4096
- Stereoscopy: On
- Stereoscopy mode: Stereo 3D
- Views Format: Stereo 3D
- Stereo Mode: [Top-Bottom | Side-by-Side]
- Squeezed Frame: [On | Off]
For file saving I have a File Output node hooked to the Image Out of the default Render Layers node.
For all 4 combinations of the bolded lines above (top-bottom / side-by-side / Squeezed / Not Squeezed) Blender renders each eye at 4096x4096, then saves a 4096x4096 top-bottom image, throwing half the rendered pixels away.
This is the behavior I would expect from Top-Bottom / Squeezed (frames arranged top-bottom,50% lossy in vertical).
What I want (and what I expected Blender to do) is to set Output Resolution to 4096x2048 and use Top-bottom / Unsqueezed to give me a 4k square image containing every rendered pixel. This would cut render times by 50% over the behavior I’m seeing, which would be significant.
Am I missing a step/setting, or is Blender not behaving per the (admittedly sparse) documentation for this feature?
