Panels¶
InteractionOps has two kinds of panels: popup panels that appear under the mouse on a hotkey and vanish when you move away, and sidebar panels docked in 3D View › N-panel › iOps tab. The sidebar tab name can be changed in Preferences › iOps › General.
TPS (Transform / Pivot / Snap)¶
Everything about how transforms behave, in one popup: gizmos, orientation, pivot point, snapping and the eight Snap Combo slots. In the UV Editor it shows UV select modes, pivot and UV snapping instead.
Hotkey: Shift+Mouse Button 4 (3D View and UV Editor)
| Button | What it does |
|---|---|
| Lock cursor, Rotate around active, Auto Merge, Auto Merge & Split, Correct Face Attributes, Keep Connected, Live Unwrap | Common tool-setting toggles |
| Create orientation | New custom transform orientation from the selection |
| Homogenize UV names | Rename UV maps on the selection to ch1, ch2, ... |
| UV cleanup | Remove all UV maps from the selection |
| Name from Active | Rename the selection after the active object |
| M / R / S | Show the move / rotate / scale gizmo |
| Orientation, rename, delete | Manage transform orientations |
| Pivot Point, Edit Origin, Only Locations, Skip Children | Pivot settings |
| Snap to, Target, Self, Align Rotation, Backface Culling, Selectable, Move / Rotate / Scale, angle increment | Snap settings |
| A – H | Snap Combo slots: click to recall, Shift+click to save |
| Smooth / Flat / Auto Smooth 30°–180° | Shading shortcuts (with MACHIN3tools installed) |
| Reload Images, display channels, Repeat | UV Editor header row |
Transform¶
A compact popup with the active object's location, rotation, scale and dimensions, so you can type exact values without opening the N-panel.
Hotkey: Ctrl+Alt+Shift+T (Object Mode)
| Button | What it does |
|---|---|
| Location / Rotation / Scale | Edit the active object's transform |
| Dimensions | Resize the object by its real size |
| Apply to Selected | Push the typed dimensions to every selected object |
| Reset Scale to 1 | Bake the new size into the mesh and reset scale |
| Ignore Modifiers | Measure the base mesh, not the modified result |
Data¶
The active mesh's UV maps, colour attributes, vertex groups and material slots side by side, with add / remove / assign buttons — a popup version of the Object Data tab.
Hotkey: Ctrl+Shift+Mouse Button 4 (3D View and UV Editor, mesh active)
| Button | What it does |
|---|---|
| Homogenize UV names | Rename UV maps to ch1, ch2, ... on the selection |
| All, 2+, 3+ ... 8 | Keep only the first N UV maps on the selection (All removes every one) |
| UVMaps list: +, -, set active by object, set active by name, sort, channel hop | Manage UV maps across the selection |
| Color Attributes list: +, -, menu | Manage colour attributes |
| Vertex Groups list: +, -, menu, up / down, Assign / Remove / Select / Deselect, Weight | Manage vertex groups |
| Materials list: +, -, menu, up / down, material picker, Assign / Select / Deselect | Manage material slots |
Modifiers¶
A modifier stack you can drive with modifier keys. The icon grid adds or manages a modifier type on the whole selection; the tool row cleans and sorts stacks; the list below edits the active object's stack row by row. Also docked in the sidebar.
Hotkey: Alt+Shift+RMB
| Button | What it does |
|---|---|
| Icon grid (click) | Add that modifier type to the selection with your preset defaults |
| Icon grid, Ctrl | Apply all modifiers of that type |
| Icon grid, Alt | Remove all modifiers of that type |
| Icon grid, Shift | Toggle viewport visibility of that type |
| Icon grid, last + button | Blender's own Add Modifier menu, for types not in the grid |
| Sort | Order stacks by the Sort Order set in preferences: rules of modifier type + optional comma-separated names (default: Geometry Nodes "Smooth by Angle" / Mirror / Array on top, Simple Deform / Weighted Normal / Triangulate at the bottom; everything else keeps its order). A Bottom of Stack rule can be flagged Pin to Last (pin icon next to the rule): its modifiers get Blender's Pin to Last and sit at the very end; modifiers caught by other rules are unpinned so they can be sorted. Also remaps geometry-nodes modifiers from .001-style duplicate node groups to the base-named group and deletes the unused duplicates (toggle in the redo panel) |
| Cleanup | Remove modifiers that do nothing (empty targets, zero values). Alt: also remove modifiers disabled in the viewport |
| Sync Vis | Make render visibility match viewport visibility |
| Cursor Target | Create an empty at the 3D cursor and use it as the modifier target |
| Active Target | Use the active object as the modifier target on the others |
| Users | Select objects whose modifiers reference the active object |
| Safe Apply | Apply transforms without breaking distance-based modifier settings |
| Adaptive Decimate | Add a curvature-aware Geometry Nodes decimate |
| Iron | Add a Geometry Nodes cleanup for folded-over flaps, sliver triangles and dangling fin triangles (the leftovers a decimate leaves behind). Mode: Merge collapses folds and slivers, Unfold relaxes fold apexes onto the surface and only merges slivers, Keep Topology moves vertices without welding so vertex count and order stay intact. Delete Fins removes flag faces glued to the mesh by one edge (off in Keep Topology) |
| Apply All | Bake the whole stack into the mesh |
| Stack row: expand, name, eye, up, down, apply, copy to selected, remove, save preset | Per-modifier actions. Alt runs the action on every selected object with the same modifier; Shift picks the variant (to top / bottom, render visibility, apply up to here) |
Collection Append¶
Turn a linked collection instance into local, editable collections: scan the source file, tick the collections you want, append. Sidebar panel (Object Mode).
