I have notice a few thing with Photoshop 3D Spherical Panorama feature. Menu 3D>Spherical panorama> has three item. The first import want to import the panorama file and scale it down in size. IMP you need to change the settings to match the panorama canvas size for it to work well. The second item wold create the 3D Spherical Panorama the same size as the file would open in Photoshop and retains the document's name in the tab. Where the Import Option would change the file extension from like .jpg to .dae in the Tab. Once the 3D spherical panorama is created the Image displayed is much softer than the jpeg. and seems to be much larger for when I scale the 3d image to match the 2d Image zoomed to 100% the soft 3D image zoom scale states 38% the 3D Projection must be huge. So the image is very soft but I can zoom way in if I need to. What is displayed is very soft but what is displayed is not the Programs actual pixels and perspective the actual pixels area in the 2d panorama projection in the area being displayed may be what has great distortion that the 3D viewer is correcting so you can edit the area. I can not say that I had a hard time cutting some floor tiles and patching out the tripod hole.
