LatLongPatcher

A full 360-degree equirectangular panorama maps longitude horizontally and latitude vertically, conventionally at 2:1. Near the poles, ordinary brushes and rectangular inserts appear stretched. Extract moves the chosen region into a more workable local view for Paint, cloning and 2D compositing. A 2:1 aspect ratio alone does not prove that a file uses the correct projection.

Build the pair with matching Order, X/Y/Z and Angle of View. The copy changes the operation direction: Extract → processing → Apply. Reprojection does not automatically require negating the angles. If the working view is animated, all linked values must match throughout the frame range.

The node has two inputs: orange Input and blue Effect Mask. It has no green Patch/Foreground socket. Apply receives the processed local picture. For compositing, branch the original panorama into an ordinary Merge’s Background and connect Apply to its Foreground. This is the graph shown in the manual.

Patch alpha defines the overlay coverage. Text or isolated strokes can be prepared on transparency and fed to Apply, leaving the original panorama outside the additional extraction/reprojection filtering cycle. If Paint outputs the entire repaired square, constrain the final repair with alpha or a final Merge mask in panorama space.

Apply 180 belongs to VR180. It is not an emergency switch for a misplaced patch. For a 360-degree pair, investigate projection, Order, angles, Angle of View and any intermediate crop or scale. Verify VR180, stereo packing, left/right eyes and headset viewing separately in the relevant project.

Final inspection covers the map seam, poles, repair boundary, alpha and motion. A static local repair does not solve parallax or replace a tracker. The examples below specify buildable graphs with explicit inputs; Resolve execution and rendering are tracked separately and have not yet been confirmed.
