System Information
Operating system:Win 10
Graphics card: GTX 1080Ti

Blender Version
Broken: 2.79b
Worked: 2.79b

I am dealing with very complex scene that contains lots of grass and trees as particle systems and couple microdisplacement stuff of overal weight 1.7 GB. My problem is when I try to render stereoscopic 3D the only output I get is anaglyphic (red-cyan in one image) - no matter what option I choose. The same goes to render passes. However, when I copy some random assets from this scene to another, clean one, rendering stereoscopy works properly. Plan is to render each view separately so I can use it in post production and 3D tv - anaglyph render is useless to me.

Exact steps for others to reproduce the error
I attached the same scene just without most assets. Set output destination, play with stereoscopy settings and press render. Every render will be red-cyan, no matter what you choose.

Can you specify exactly which part is not working?

Render animation output can be set to save anaglyph or individual views.
The image editor can display anaglyph or separate left/right views, with a toggle in the header.
When saving from the image editor, you can also choose anaglyph or individual views.

Also please test the latest daily build of 2.79 or 2.80 to see if the problem is still there:

My goal is to render two separate images (L,R) so I can use them in post production or any stereoscopic software. Whether I choose "top to bottom" or "individual" the output (files that land on my drive) are always anaglyphic (red-cyan). I tried it on blender 2.79.7 and it's still there.

edit*

From image editor I can save as individual. Only that way.

But can you specify which of those 3 things you are doing, and which ones fail?

I noticed just now, when I plug render layer node directly into composite node the output of it is L and R views separately. However other render passes are still anaglyphic.

My observations for the file output node :

When selecting OpenEXR Multilayer per view an OpenEXR Multi layer is created (_L, _R). I didn't see the option to save them as Multiview OpenEXR files what is supported when using the compositor node.
When selecting any other file format (including OpenEXR) the views are merged using the settings in the node. As these settings cannot be adjusted by the user it defaults to Anaglyph Red-Cyan.
(Unrelated) There is an inconsistency in the File output node where the base is used as folder or as file.

Seems to be that the node reads the defaults (from the node themselves), but users don't have the possibility to alter these. I would suggest that the user would be able to set the export settings when multi view is active for the scene. And use a similar panel as in the Output properties panel eg template_image_views.

Panel used to work once (years ago), but due to NULL pointer pre-check it is not rendered anymore.
