View XPort (aka VXP or V.X.P.) is a Blender addon aimed to extend 3D viewport abilities.

(Formerly named “View3D Exponent” and “Exponent” before v3.)

Target Users
– who require powerful and fast view saver

– who require CAD-style quad view

– who suffer from accidental view rotation

Require
Blender: 2.93 LTS, 3.2, with latest update

Essential Module
– View Channels
The most common CAD/DCC feature but long missing from Blender. Combined with menu/button/hotkey, view channels save and load view status instantly, thus become powerful modeling helper.

View channel label could be displayed as HUD info just like other CAD/DCC.

– Lock View Rotation X
Lock mono view in “soft” way. This lock middle mouse orbit, but allow viewpoint change and perpective change with numpad keys. This is suitable for modeling.

Lock quad view in “hard” way. This lock region data, and hence viewpoint change and perpective change are disabled also. This is suitable for checking side views.

– Toggle Quad View X
When toggling between quad and mono view, the viewpoint and lock state are kept unchanged into following view.

When toggling from quad to mono and back to quad view, the position of view channel (specific sub view in quad view) is kept unchanged.

– Smart Middle Mouse
Middle mouse works as Pan or Orbit depending on lock state of current view. This is based on assumption that Pan is prefered in locked state, and Orbit for unlocked state.

In same quad view, this feature handle 3d region and side views separately. Middle mouse works as Pan on locked sub view, and as Orbit on unlocked sub view.

– Smart Region Overlap
Auto enable region overlap in mono view, and disable it in quad view. This guarantees both views always have most efficient layout.

Memorize Module
– Versatile work modes
Save and load views in linear order (Linear mode), arbitary order (Static mode) or a combination of both (Combo mode). No data loss would happen on these modes changing.

– Fast option for linear mode
This mimic undo/redo logic of common editors. Automatically remove obsoletes, duplicates and gaps from linear slots, and save unsaved current view to first slot.

(“Obsoletes”, here means saves from the first slot to the latest loaded slot. In common editors, they are treated as abandoned historical steps.)

– Powerful UI
With HUD info and hotkeys, view saving and loading is super fast. While popover and sidebar panel are also provided for more rich features.

– Save camera data
Camera’s properties are saved in camera view, and can be restored to original camera if possible.

– Save quad views
Quad view’s all four sub views, including camera view if existing, can be saved and restored simultaneously.

– Restore ortho axis name
When orthogonal view restored, its axis name (Fron/Left/Top, etc) is correctely restored.

With the transition to v3.4.0,
it is recommended to right-click any button in the new Matrix Grid to manually assign your preferred F-key shortcuts,
as the legacy hardcoded bindings have been removed for stability.

Change: “Global HUD Level” set to Level 1 by Default to reduce visual clutter.
Better: redesigned UI to “View Master 5.1” with chunky tactile layout and hierarchical sub-panel grouping.
Better: replaced vertical slot list with responsive 4×4 “Matrix Slot Grid” utilizing grid flow.
Better: intelligent button highlighting (Red alert state for Quad-locked Ortho views, Blue depress for general locks).
Fix: scene HUD level now correctly syncs with global user preference upon initialization.
Fix: preferences panel now whitelists and displays only relevant active hotkeys to remove ghost entries.
Better: migrated all operator overrides to modern “context.temp_override()” for Blender 5.1 compatibility.
Add: lazy initialization for Smart MMB, ensuring keymaps build correctly even if startup callbacks fail.
Fix: implemented hasattr() checks for camera cycles and stereo attributes to prevent fatal AttributeErrors.
Fix: added “Void Viewport” safety check in load_view to prevent viewport coordinates resetting to zero.
Fix: Quad View exit logic now scrubs clip planes and box clips before merging to prevent mono view leaks.
(Identified rapid-fire quad-view toggle 0xc0000005 crash as native Blender Window Manager limitation)

v3.3.0 (2026-03-30) OLD 
Warning: Minimum Blender version raised to 4.0.0. This version is likely not compatible with Blender 3.x or earlier.
Change: replace legacy context override API with context.temp_override() for Blender 5.0+ compatibility
Fix: HUD overlapping with overlay text/statistics corrected (increased vertical compensation)
Fix: remove deprecated DPI parameter from blf.size() calls, fixing font rendering warnings
Fix: update UI style property from widget_label.points to widget.points for Blender 5.0
Change: small code tweaks for Blender 5.0 API compliance 

VFXMED NOTE :- THE OFFICIAL UPDATE FOR BLENDER 5 DOESNT EXIST SO A MEMBER FIXED COMPATIBILITY USING AI – YOU CAN USE IT ON BLENDER 5.1.0 NOW.
