Note: selection and the undo stack is maintained between tools.

Pie menu

Press `, Q at any time to show the tool pie menu.

Quick Tool Shortcuts

Pressing the tool’s quick shortcut will temporarily switch to that tool. RetopoFlow will switch back to the previously selected tool once you are done.

Ctrl+R : Loops
K : Knife
C : Tweak
Z : Relax

Universal Shortcuts

The following shortcuts work across all the tools, although each tool may have a distinct way of performing the action. For example, pressing G in Contours will slide the selected loop.

Ctrl+LMB, Ctrl+LMB+Double : create new geometry with current tool / apply relax or tweak
LMB+Click, Shift+LMB+Click : select single
LMB+Drag, Shift+LMB+Drag : selection painting
LMB+Double, Shift+LMB+Double : smart selection
Ctrl+Shift+LMB+Click : select along shortest path
A : select / deselect all
Alt+A : deselect all
Ctrl+I : invert selection
H : hide selected geometry
Shift+H : hide unselected geometry
Alt+H : reveal hidden geometry
LMB+Drag : transform selection when mouse hovers selected geometry
G : grab and move selected geometry
R : rotate selected geometry
S : scale selected geometry
Shift+S : smooths edge flow of selected geometry
Backspace, Delete, X : delete / dissolve dialog
Ctrl+Backspace, Ctrl+Delete, Ctrl+X : delete / dissolve pie menu
Ctrl+Z : undo
Shift+Ctrl+Z : redo

General selection has a few options to help with selecting troublesome vertices (ex: just below surface of source). When Occlusion Test is enabled, geometry that is occluded by the source(s) are not selectable. When Backface Test is enabled, geometry that is facing away are not selectable. Disable these options to make geometry easier to select.

Selection options

Pressing Backspace, Delete, X will bring up the Delete/Dissolve/Collapse dialog, allowing you to delete/dissolve/collapse the selected geometry. Pressing and holding Ctrl+Backspace, Ctrl+Delete, Ctrl+X will bring up a Delete/Dissolve pie menu, which has fewer options than the dialog but is generally faster.

General Options

The UI Scale option controls how large or small RetopoFlow will draw things. Larger numbers produce larger fonts, thicker lines, larger vertices, etc.

If the Auto Hide Tool Options is checked, the options for the currently selected tool will be shown, but all other tool options will be hidden.

Target Cleaning

The Snap Verts buttons will snap either All vertices or only Selected vertices to the nearest point on the source meshes.

The Merge by Distance will merge vertices into a single vertex if they are within a given distance.

View Options

The Clipping options control the near and far clipping planes.

The Theme option changes the color of selected geometry.

The Target Drawing options control the rendering of the target mesh. The Above and Below options control transparency of the target mesh. Vertex Size and Edge Size control how large the vertices and how think the edges are.

Symmetry Options

The X, Y, Z checkboxes turn on/off symmetry or mirroring along the X, Y, Z axes. Note: symmetry utilizes the mirror modifier.

When symmetry is turned on, the mirroring planes can be visualized directly using Plane option, or indirectly by coloring the sources choosing either the Edge or Face option. The Effect setting controls the strength of the visualization.
