New Operators

• Added standalone operator for Relax that can even be used outside of Retopoflow

• Has all the same masking and snapping options as the brush version

• Includes unique options for retaining / reconstructing the desired shape

• Works great with proportional editing

• Improved Relax performance

• The default hotkey is Shift R

• Added operator for evening selection that also works outside of Retopoflow

• Similar to Relax but faster to use when adjusting spacing and improved for edge loops

• Works for any number of selected edge loops, non-loop edges, and faces

• Optionally preserves sharp angles

• The default hotkey is Shift Alt R

• Added operator for inserting diamond junctions that also works outside of Retopoflow

• The default hotkey is Ctrl Alt B

• Added operator for twisting loops that also works outside of Retopoflow

• It automatically finds cross-sectional loops in the selection and twists each one independantly

• All vertices that are not on complete loops are properly interpolated

• Works great with proportional editing

• The default hotkey is Alt T

• Added new Auto Fill operator that can be used outside of Retopoflow

• Described below in the Patches section

• The default hotkey is F

• Added new Edit as Curve operator for adjusting any selection with Bezier handles

• Works outside of Retopoflow tools

• Works the same as the curve handles in PolyStrips and Strokes described below

• The default hotkey is Alt C

Patches

• Added new Patches tool for quickly filling areas with quads

• Select boundary edges to see a preview of the fill

• Ctrl LMB on vertices to add or remove corners as needed

• Hit Enter, Ctrl LMB (not on the selected vertices) or F to accept the fill

• Select the edges around a hole to fill it

• Select boundary edges to face step them

• When the selection ends in a corner, it will step and connect similar to the F2 add-on, but this works for entire loops not just single faces

• Ctrl Scroll to step multiple times

• Shift Scroll to adjust the step width

• Select perpendicular boundary edges that form an L shape to fill it

• Select parallel boundary edges facing each other to create a bridge

• Select three boundary loops with four corners that form a U shape to fill it

• Select any n-gon to replace it with a patch

• Select a corner vert to make a quad, same as the F2 add-on

• Ctrl Scroll can be used to cycle through solutions when multiple exist

• Shift scroll before or after filling a patch to rotate the solution

• Alt R on any selected faces to rotate the topology in any tool

• Solutions with triangles and n-gons are supported when quad solutions don’t exist

• non-quads are highlighted and very obvious

• Added new hotkey F to access Patches from any tool

• Tapping F will auto-fill the selection using the Patches algorithm

• Holding F will temporarily switch you into Patches, giving you an interactive preview of the fill, which you can adjust as needed and accept with LMB or Enter

• The Patches fill operator can be used outside of Retopoflow by pressing F, from the Retopoflow context menu, or the Edge or Face menus.

Contours

• Added new source processing method, SDF, to Contours

• It is much faster than Walk but slower than Fast

• It is slightly less accurate than Walk but much more accurate than Fast

• It can handle flipped normals, split edges, and overhangs just fine

• Added Shift Scroll hotkey to twist in Contours

• Added Ctrl Scroll after extruding in Contours to adjust segment count

• Added Curvature and Space Evenly controls to Contours that determine where new points are placed

• Added Refinement option to Contours Fast method that improves quality without much overhead

• Exposed the Contours Walk method source object cache so it can be managed manually if needed

• Increased max span count in Contours

PolyStrips

• Added Ctrl and Shift Scroll operators to adjust segments and width at any time in PolyStrips

• This is also a standalone operator that can be used outside of Retopoflow

• PolyStrips now has insert size methods similar to Strokes

• The default, Snapped, properly interpolates when drawing between any two quads

• Improved edge placement when creating strips

• PolyStrips now snaps to adjacent geometry, so you can draw alongside existing edges

• PolyStrips face sizing now matches the faces you snap to or from by default

• Significantly improved PolyStrips curve handles

Strokes

• The curve handles are now available when working in Strokes and PolyPen as well

• Expanded the curve handle system to work with edge loops and patches of faces

• Hovering over a control point and pressing v toggles the handle type

• Toggling the handle type to or from Vector automatically inserts or removes corners

• Handle visibility can be toggled with Alt C

• Stokes now snaps its span sides to nearby connected vertices

• This makes it so Strokes can fill holes without creating overlapping verts

• Strokes now places verts at sharp angles in the drawn stroke

• Strokes now projects in world space, fixing spacing and redo issues

• Strokes can now use world space units as the span length

• Closed loops drawn with Strokes have a new slider to make them perfectly circular

• Switched Strokes and PolyStrips brush size hotkey to Shift F to free up F for filling

• All brush based tools can now use the bracket keys to change the size as well

• Fixed incorrect brush preview size when adjusting radius in non-default UI scales

Tweak and Relax

• Added Nudge, Nudge Loops, and Pinch / Magnify modes to Tweak tool

• Nudge is now the default instead of Grab

• You can hold Alt to quickly toggle loops mode in Nudge

• Tweak and Relax now default to affecting only one mesh island at a time

• Can be changed in the Masking options

• Relax is now significantly faster

CAD Snapping

• Added experimental low poly hard surface / CAD snapping

• Enabled via the new Snapping menu under Source Feature Detection

• You can snap to sharp angles, creases, seams, or edges marked as sharp

• Works while grabbing, brushing, or creating new vertices in all tools

• Inludes a new caching system for the source objects

• Can be slow in heavy scenes, so it is only recommended only for low detail scenes for now

Misc.

• LMB drag away from geometry now falls back to the active selection tool

• Can be disabled in the Tweaking menu under Selection

• You can change the fallback tool with Blender’s Alt W hotkey

• All Retopoflow tools now respect Blender’s Alt+B clipping region

• Useful for isolating areas while working

• Tools statusbar now shows the result of Blender operations such as Merge by Distance

• Added new custom icon for Loops tweaking in tool header

• Cleaned up tool header UI

• Added more tool options to the pie menu (default W)

• Improved extrude vs. knife decision tree in PolyPen

• Improved automatically switching between screen space and world space snapping

• Improved normal calculations when transforming or creating new geo

• The option to turn off recalculating normals moved to the new Snapping menu

Fixes

• Fixed crash and removed hotkey block for Maximize Area

• Fixed performance issues when using some pen tablets or non-official Blender distributions

• Fixed performance issues when frequently using the Relax and Tweak quick switch hotkeys

• Fixed proportional editing circle size and location

• Fixed non-uniform scale issues when drawing in PolyStrips

• Fixed wire and solid mirror display in Blender 5.2
