How Session Recovery Works
When you extract a perspective view with Edit This View, PanoView Editor embeds persistent metadata directly into the Photoshop document. This metadata records the camera orientation (Heading, Pitch, Field of View), the aspect ratio, and unique internal session identifiers linking the rectilinear edit document back to the master panorama.
Whenever an edit document or panorama is active, PanoView Editor validates this metadata against the live Photoshop layer stack. If layers were renamed, deleted, or converted outside the plugin, protective alerts display in the session list to prevent damaged reprojections.
Session health indicators and recovery options within the 360 Edit Sessions panel.
Session Cannot Find Its Panorama
If the edit document is currently open in Photoshop, but its parent panorama has been closed, the session status displays Panorama Closed.
- 1.Do not close or discard your edit document. Your artwork modifications are safe inside it.
- 2.In Photoshop, select
File > Open...and open the original panorama file. - 3.Switch back to the edit document tab. PanoView Editor automatically re-establishes the session handshake.
Editable View Missing
The alert Editable View Missing occurs when the dedicated artwork layer inside the edit document cannot be identified by name.
How to Restore the Editable View
PanoView Editor expects your modifications to reside in a layer or group named exactly 360 Edit positioned directly above the background reference.
If you renamed the layer, restore its original name.
If an intact earlier version of the edit document is available, return to that version before the editable layer was removed.
Otherwise, create a new perspective edit view from the panorama rather than attempting to rebuild internal session connections manually.
Editable View Was Rasterized
If the edit document or its embedded Smart Object components were flattened or rasterized into a single background layer, PanoView Editor displays Editable View Was Rasterized.
PanoView Editor requires structural separation between the unmodified background reference and your new pixel edits. Flattening merging destroys the reference baseline required for differential blending.
Safe Recovery: If an intact earlier version of the edit document is available, return to that version before the editable structure was altered. Otherwise, create a new edit view from the panorama rather than manually reconstructing internal session data.
Multiple Editable Sources
The warning Multiple Editable Sources Found indicates that more than one layer or group inside the document contains the naming signature or identifier expected for editable content.
To avoid accidentally omitting layers or merging conflicting layer hierarchies during reprojection, PanoView Editor halts until the ambiguity is resolved.
Ensure the edit document contains only one unambiguous editable source layer or group associated with the session. If structural ambiguity cannot be resolved safely, preserve your retouched pixels and create a fresh edit view from the panorama.
Multiple Panorama Results
The status Multiple Panorama Results Found occurs when you have duplicated the panorama document in Photoshop (such as via Image > Duplicate...), resulting in multiple open documents sharing the same internal session identifier.
Ensure only one instance of the matching panorama document is open in Photoshop. Close duplicate or copy document tabs, verify the correct panorama is open, and then run Apply View Edits.
Panorama Size Changed
The warning Panorama Size Changed indicates that the source panorama was resized or cropped after the perspective view was extracted.
Perspective extraction matrices rely on precise pixel mapping relative to the panorama dimensions. Changing the source resolution breaks spatial alignment.
Remediation: Revert any canvas size or crop adjustments to match the original panorama document dimensions, or generate a fresh perspective view from the current panorama geometry.
Reference Needs Attention
The alert Edit Reference Needs Attention indicates that the locked Background/Reference layer at the bottom of the edit stack was modified, transformed, or unlocked.
PanoView Editor calculates pixel differences by comparing your artwork against this untouched reference layer. If the reference layer is painted on or repositioned, differential blending cannot determine which pixels are intentional edits.
Remediation: Ensure the reference layer is unmodified, kept at the bottom of the layer stack, and locked.
Reopening & Recovering Sessions
Because session metadata is written directly into your Photoshop PSD or PSB document, sessions survive Photoshop restarts and system reboots:
When Delete Is Available
The Delete action removes a perspective view entry and its metadata from the session list:
Restriction While Open: You cannot delete a session view while its corresponding edit document is currently open in Photoshop. You must save or close the edit document tab before deletion is permitted.
Explicit Confirmation: Deleting a session prompts for explicit user confirmation to prevent accidental loss of saved perspective angles.
Non-Destructive to Panorama: Deleting a session view removes the perspective reference entry; it never deletes or damages the source equirectangular panorama canvas.
Safe Recovery Checklist
- Source panorama document is open in Photoshop.
- Panorama canvas dimensions match original extraction size.
Background/Referencelayer is locked and unmodified.- Edits are placed on or inside the
360 Editlayer/group. - Only one open panorama matches the session ID.
