For Blender 3.6 and 4.0 up use latest DrawXray 3.8

Free version of Draw Xray add-on will help you to draw retopo mesh on top of your high-poly mesh, without problems of build-in blender xray (no proper back-face culling).

How to use:

  • Install DrawXray like any other Blender add-on - see Blender docs
  • In 3D View Top Bar > Viewport Overlays press 'Enable Xray' - if you go to mesh edit mode, you will se new overlay rendered on top of your mesh
  • Depth Bias - will determine how much your lowpoly object will be rendered in front of other objects. Set it to 0 to get default blender behavior.
  • You can change Face Color and Highlights Color;
  • Xray Overlay can be enabled in following modes: Edit, Sculpt, Paint, Object (default - Edit; shift+Click to select multiple modes).

Paid version comes with snapping features:

  • better approximation of high-poly mesh, compared to blender build in snapping,
  • support for retopology with subdivision modifier - DrawXray will negate mesh shrinking effect caused by that modifier,
  • linking pairs of hipoly and lowpoly meshes, etc

Details about snapping features were shown in video below:

Update 2.3 Blender 2.8 only (23.08.2019)

  • fixed crashes on scripts reload, and other bugs.
  • by default per object snapping is now set to 'Global' . Saves few clicks: when you enable global snapping, all objects will use now global target. You can still change it per object in: 'Object Viewport' panel to: Disabled or Local (different snap target for each object)

Update 2.7 Blender 2.8 and 2.9  (19.11.2020)

  • 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 2.8 for Blender 2.93 and 3.0 (01.12.2021)

  • Added compatibility with Blender 3.0

Update 2.9 for Blender 2.93 and 3.x (12.09.2022)
