Finally managed to work it all out. As usual something simple. In photo director Right click image mark as 360. Boom.
This is how I did it.
Took 360 pano with Mavic Air. Moved pano photos to pc.
I used Microsoft ICE to stitch the photos. This was not the right scale for 360 photos in photo director. So then I needed to add extra sky to make the image 2:1.
I used 'Gimp' Re-sized the canvas\image to 19968 wide by 9984 high. Moved the image down so that the fuzzy stuff was at the top. Saved and exported. You can add your own bit of sky in if you have a good image etc. I didn't.
I then imported to Photo Director. Clicked to make 360 and then used the Little Planet function. The fuzzy bit at the top turned out to default as white.
You can see the result attached.
Thanks for the help.
