QRemeshify

{ Download | Forums | Issues }

A Blender extension for an easy-to-use remesher that outputs good-quality quad topology

Based on QuadWild with Bi-MDF solver which is based on QuadWild

Features

• Good-quality quad topology even with basic usage
• Supports symmetry
• Guide edge flow with edges marked seams/sharp/material boundary/face set boundary
• Options for advanced fine-tuning available
• No external programs to download or run

Example

Suzanne 3D Model

Model from Elizaveta

Model from Wildreamz

Try it

1. Add > Mesh > Monkey
2. Add subdivision modifier with 2 levels
3. Add triangulate modifier
4. Open QRemeshify panel, disable Preprocess, set sharp angle threshold to 25, enable symmetry in X-axis

Requirements

• Blender 4.2 and above
• Windows (still testing Linux and macOS)

Installation

1. Download the zip file according to your OS from Gumroad or from Releases
2. For Blender 4.2 and above, go to Edit > Preferences > Addons and click the arrow pointing down on the top right
3. Click on Install from Disk... and select the downloaded zip file
4. Ensure the checkbox is ticked to enable QRemeshify

Usage

QRemeshify can be accessed from the 3D view N-Panel (Press N in 3D view) while in Object mode

Please remember to save often, time taken for remeshing is dependent on many factors and may take an unexpectedly long time

Settings

Advanced Settings

Other than Debug Mode and Use Cache, advanced settings are passed straight through to the underlying QuadWild Bi-MDF and QuadWild library and are either undocumented or too complex for me to understand. They are still made available here for experimentation and fine-tuning.

Tips

Find and share more tips at Discussions

• Slower for more complex shapes eg. lots of cloth folds, try separating into smaller, simpler parts
• Having an even distribution of tris seems faster, either manually decimate and triangulate or enable Preprocess to help with this
• Time taken is proportional to number of faces, decimate to <100k tris would be a good start
• Needs sufficient geometry to work with to get a good topology, roughly >1k tris
• Loose geometry may need to be separated into individual objects, Edit mode > P > Separate by loose
• Use edges marked as sharp or UV seams to influence edge flow
• Use cache to only run quadrangulate step if previous steps have been run once before, for speeding up while tweaking advanced settings
