Quad Fill

Tachyon Studio in Modeling

TACHYON STUDIO   /   QUAD FILL 1.0.0

Fill the gap.
Keep the flow.

Bridge borders. Repair openings. Finish the form.

Turn difficult mesh gaps into editable, quad-dominant geometry—with a live preview and control over the transition.

BLENDER 3.0–5.2CLASSIC + ADAPTIVEEDITABLE MESH
Quad Fill: bridge borders, fill holes and shape caps

Keep the borders you built. Shape the surface between them.

01

Bridge

Connect open chains or closed loops—even when their edge counts differ.

02

Patch

Fill a hole and tune the new surface to follow the surrounding shape.

03

Finish

Complete inner corners, add support geometry, or close a loop toward a point.

SIX WAYS TO CLOSE THE GAP

Made for the missing piece.

From surface transitions to end caps, see the topology Quad Fill creates.

AMBER · SELECTED BORDER CYAN · GENERATED FACES

Actual Quad Fill 1.0.0 output. Studio colors and presentation are explanatory overlays, not the default add-on interface.

01   /   SURFACE TRANSITIONS

Different counts. One connection.

Animated demonstration: connect a 10-edge border to a 4-edge border
10 → 4 EDGES

Join differently sampled panels or shells without rebuilding the borders. Add rows and shape the transition.

02   /   DUCTS & CONNECTORS

Build the transition.

Animated demonstration: a 16-to-8-sided tube connection
16 → 8 SIDES

Bridge closed loops with different counts. Use Classic tube seams, twist and smoothness to control the connection.

03   /   CURVED SHELL REPAIR

Carry the curve across the gap.

Animated demonstration: fill a curved shell opening
SURFACE CONTINUITY

Fill the boundary, adjust smoothness and inspect how the new patch follows the surrounding curvature.

04   /   SUBDIVISION PREPARATION

Give the border support.

Animated demonstration: a filled panel with a narrow support ring
SUPPORT RING

Add a ring around a filled hole or support rows along a bridge. Tune the width to the shape you are building.

05   /   HARD-SURFACE PANELS

Complete the missing corner.

Animated demonstration: complete an inner L-shaped panel corner
INNER CORNER FILL

Fill an inner L-shaped corner as a grid, or close across a V-shaped border. Outer corners that would cover existing faces are refused.

06   /   HANDLES & END CAPS

Bring the form to a close.

Animated demonstration: close a 24-edge ring toward a selected point
LOOP → POINT

Close a loop toward a selected point, reducing the ring toward a small pole rather than sending every border edge into one dense fan.

A FAMILIAR EDIT MODE WORKFLOW

Select. Preview. Fill.

1

Select the border

Enter Edit Mode and select the relevant border edges. Open N-sidebar → QuadFill.

2

Shape the transition

Choose Classic or Adaptive. Adjust smoothness, extra rows and support geometry while checking the live preview.

3

Commit and keep modeling

Use Shift+F for a fill or Ctrl+Shift+F for interactive adjustment. The result stays editable mesh geometry.

COMPATIBILITY

Built for Blender.

Designed for Blender 3.0–5.2. Installation and background mesh-operation checks passed on Windows in 3.0.1, 3.3.21, 3.6.23, 4.1.1, 4.3.2 and 5.2.0 LTS.

Not every intermediate version, operating system or foreground interaction has been tested.

TOPOLOGY NOTES

Know the limits.

Quad Fill is quad-dominant, not an all-quads guarantee. Odd counts can need a triangle or another topology compromise.

It does not retopologize entire sculpts. Branched, intersecting or already-filled selections may need cleanup first.
