Facebook – Fix Error: Failed to Create Your 3D Photo

3dfacebookphotos

I created a stereoscopic 3D photo from scratch using mirrors & depth map generation on an old camera.

I've tried various ways to upload it to Facebook. However, I always get errors.

How can I upload a grayscale depth map + RGB JPG to Facebook and get it to be in 3D?

This pair fails inexplicably:

NONE of these work:

Blurred from GIMP:

More RAW from Stereo Photo Maker:

Pixelized & Posterized from GIMP:

GIMPEnhanceSymmetric Nearest Neighbor doesn't seem to help either, oddly:

And even hand sanitizing that still fails:

Even with a heavy median blur to join like-regions together, no luck:

I noticed there was a canvas size issue in GIMP, so I resized the photo but it still didn't work:

However, this works fine (use the grayscale as the RGB layer for testing):

It definitely is the aspect ratio. I made all variants with same result (error) on a vertical image and then changed the size to a "square-ish" shape (750x918px) and it worked.
