Cylinder Resample for Blender

About

Blender addon for 5.0+ for resampling cylindrical mesh topology:

Adjust the vertex count of cylindrical edge loops while preserving the overall shape. Cylinder Resample rebuilds rings with a consistent resolution along straight or curved tubes, reducing artifacts from uneven topology.

UPDATE 1.2 AVAILABLE, READ NOTES BELLOW

Usage

Cylinder Resample add-on
Ctrl + E → Cylinder Resample (Edit Mode)
Select edge loops/rings that define the cylindrical section
Set the desired vertex count and confirm
Works on straight cylinders as well as bent pipes (multi-segment elbows, S-curves).

Features

resample cylindrical loops to a target vertex count
preserves overall shape and radius along the tube
stable ring alignment across curved sections (minimizes twisting)
rebuilds clean, evenly spaced topology
supports continuous selections across multiple connected rings
attempts to maintain shading consistency where possible
works only with quads and with cylindrical objects being separate mesh element

Important:

May produce incorrect results on low-poly or irregular cylinders. Works best with evenly spaced quads and clean, circular edge loops
Breaks UV

Installation:

Download py file then instal it in Blender Preferences → Addons

Update 1.0 (04 May 2026)

First version of addon. Tested only on Blender 4.5.9 and 5.1 Possible tweaking will be applied in future if needed.

Update 1.2 (19 September 2026)

Now interactive - adjust the resolution in real time, with live preview,
Supports circular, oval and irregular cross-sections (change shape type from Circular to Smooth by using shortcut M)
Works on hollow pipes with wall thickness - inner and outer walls are resampled together,
Handles both open-ended and closed loop tubes,
Fixed a lot of bugs on complex geometry, including tubes that bend in multiple directions,
