I have stereoscopic photographic images and movies (not generated by Blender) that I would like to display in a scene. Each image is appended by _L and _R. I am able to import them into the background, image editor and UV Editor by clicking the multi view option. It appears that the only way to display these external stereoscopic images in a stereoscopic blender render is to apply them as an image Texture to a mesh, such as a plane. The difficulty is that the stereoscopic image displays correctly in the UV Editor (in stereoscopic mode), but when unwrapped onto the mesh plane it is no longer truly stereoscopic - instead blender simply uses the left image for both the left and right outputs. Is is possible to render such a stereoscopic pair in Blender?
This is the type of stereoscopic image I am trying to show - the left images are appended by _L, and right by _R. Blender understands this notation and format if you click the 'multi view' option when you open the images; and it does correctly show them as true stereoscopic images for background images, reference images, in the Image Editor and even in the UV Editor, but I cannot figure out how to get them to display properly on a plane.
