If you find yourself needing to fix your down shots or any other portion of your panorama, you will find Pano2VR’s Patches Mode a helpful feature and we’ve just made a tutorial to help you show how to add and edit patches.
Patches lets you extract a portion of the panorama that is not distorted. Just edit that extracted patch and Pano2VR will automatically update the panorama. Of course you’re not limited to just the down shot. A patch can be applied to any area of the panorama.
