Tris to Quads

Triangulates the selected faces and immediately merges them back into quads, all in one undo step with one redo panel. Use it to re-flow imported or boolean-heavy geometry with consistent diagonals while respecting seams, sharp edges, UVs and materials. Edit Mesh mode.

Hotkey: Not bound by default — assign a key in Preferences › iOps › Keymaps, or run it from the iOps pie / operator search. Also available: iOps Pie › Tris to Quads.

Options

• Quad Method / N-gon Method — how faces are split into triangles first.
• Max Face Angle / Max Shape Angle — how far from flat and square a pair of triangles may be and still merge.
• Topology Influence — how much existing edge flow steers the merge.
• Compare UVs / Colors / Seams / Sharp / Materials — do not merge across these boundaries.
• Deselect Joined — deselect faces that got merged.

Tips

• Quads in the selection are split and re-merged too, so their diagonals may change.
