There are many ways to fix the tilt of a 360 image. Photoshop can adjust orientation with offset adjustment. Affinity Photo is also popular. If your viewer supports XMP data, you can edit the metadata. For example, in Facebook and most social media applications, simply drag the default orientation with your mouse.
I will show you a technique to use Hugin. It’s not necessarily a best practice as it’s a bit cumbersome. However, this technique may have a place in your toolbox if your viewer does not support XMP data. This technique works with any application, even applications that do not support pitch, yaw, and roll adjustments with XMP data.

To save you time, I’ll repeat that you don’t need this technique if your application is uploading a 360 image to Facebook or most social media sites. Facebook adjusts the XMP data using your mouse to set the default image.
