I've been trying FB's 3D thingy out with mixed results - some have come out quite well, some are pretty wretched. It does seem like each case is a unique one. I don't use Omnivert, just make the depth map and adjust it by posting on FB using the "Only Me" settings. I post from desktop, not the phone, so I can keep working the depth map and seeing how it looks. And yes text is very difficult to get right!
