For Blender 4.2+ for older blender versions, please use old versions of DrawXray
Addon for Blender 4.2+, that will show retopology overlay on top of your mesh.
Pros compared to build-in Blender retopo overlay:
easier to see which parts of your retopo mesh protrude out of your hipoly mesh, and which are below hipoly surface (build-in retopo overlay makes it impossible to see – if your mesh it above or below highpoly surface – see image below)
more customizable
faces overlay color, opacity, edges opacity,
supports drawing in various modes: Sculpt, Edit, Paint, Object mode,
option draw with-or without modifiers
Cons:
slower – it is coded in python, so it wont be as fast as native C++ code.
With Blender build-in retopo overlay it is impossible to tell if lowpoly mesh is under or above highpoly geometry. DrawXray makes it is easier to tell which parts of lowpoly mesh have to be pushed in or out.
Paid version comes with snapping features:
better approximation of high-poly mesh – thanks to taking into account mesh curvature (sink lowpoly mesh into valleys, push outside on peaks and keep retopo mesh close to flat surfaces) – see video below,
support for retopology with subdivision modifier – DrawXray will negate mesh shrinking effect caused by that modifier,
quad stroke drawing feature (new in DrawXray 1.7.0)
linking pairs of hipoly and lowpoly meshes, etc
addon draws more uniform edges now
more snapping options (based on shrink wrap modifier)
Simplified UI (there is no longer separate panel in object properties)
Update 4.2.0 for Blender 4.2+ – Released 12.1.2025 (for version with snapping)
You can resample drawn quads with MMB+Scroll,
you can extrude multiple edges now,
added ‘2d Matching’ for screen space calculations and detection of valid face edges,
Wrap Strip – you can resample it now in both directions,
Shift+Q – is used now for smoothing selected geometry,
undo is broken into stroke welded/non-welded segments now,
Brush uses multiple samples to pick smoother normal from highpoly mesh,
