This page details how to set a Blender image for exporting as Equirectangular Panorama, and how to edit its exifdata so that it will be automatically read as a 360 degree image in Facebook.
Contents
Blender settings
- When exporting a Blender scene, remember that your camera should be in the very position of the intended viewer within the virtual "room" or space.
- Camera setting should be Panoramic > Equirectangular
- Render setting should be for an image in a 2:1 ratio (not exceeding 6000 x 3000px)
- Save the image in JPG format
Installing ExifTool on OS X
From Exiftool's website: "ExifTool is a platform-independent Perl library plus a command-line application for reading, writing and editing meta information"
There is more Installation information here: http://owl.phy.queensu.ca/~phil/exiftool/install.html
Its easy to install it on Mac!
- Download the ExifTool OS X Package from the ExifTool home page - http://www.sno.phy.queensu.ca/~phil/exiftool/
- Install as a normal OS X package. (Open the disk image, double-click on the install package, and follow the instructions.)
You can now run exiftool by typing "exiftool" in a Terminal window.
By default when you open Terminal you'll be in the home folder and it will look something like this:
Last login: Mon Nov 28 11:31:11 on ttys000 dbbd:~ debbieding$
To look at what files/directories are inside your Home Folder (a folder is also known as a directory), you can use ls
to list out the items in your Home folder. You can also use ls -l
to see it in more detailed list form.
You need to navigate to the folder that your image is in:
- From the default when you first open Terminal, if you type
cd
and press the Return key, it will go back to your Home folder. -
cd ..
goes one level up -
cd <directoryname>
goes one level down into a directory called <directoryname> within your home folder - If your image is on your desktop, in order to go from the default home folder to desktop, you usually just type
cd desktop
. Note how the line on screen now looks something like "dbbd:desktop debbieding$" instead of "dbbd:~ debbieding$" (the tilda ~ is now replaced by the word "desktop") - list out the items using
ls
and confirm that your image is within the folder. - run exiftool with this line to change your photo's exif data:
exiftool -ProjectionType="equirectangular" blenderrender.jpg
Your image is now ready for upload to facebook! It should be rendered as a 360 photo.
- Useful tip: to cancel a command line process in Terminal press Template:KeypressTemplate:Keypress or Template:KeypressTemplate:Keypress
Requirements for creating Facebook 360 Images
- Photo should have 2:1 aspect ratio
- Maximum file dimensions of 6000 by 3000 px
- Exif XMP tag, "ProjectionType=equirectangular"
Tricks
It was found that setting the Make to "RICOH" and Model to "RICOH THETA S" will also create images that get 360 treatment in Facebook - once the image is in a 2:1 aspect ratio. This is because its a popular pano camera.
