Draw Xray

402 ratings

Addon for Blender 4.2+, that will show retopology overlay on top of your mesh. The paid version comes with custom snap engine and retopo stroke tool.

Free Version (addon):

Video guide from Jayanam - showing the retopo Xray overlay (feature in both free and $ version)

Pros compared to build-in Blender retopo overlay:

  • This tool allows for clearer visualization of how your retopo mesh interacts with your high-poly model. You can easily identify which areas of the retopo mesh protrude beyond the high-poly surface and which areas lie beneath it (unlike built-in retopo overlay, which obscure this information)
  • customizable: faces overlay color, opacity,
  • supports drawing in: Sculpt, Edit, Paint, Object modes
  • option draw with-or without modifiers applied

Cons:

  • slower - it is coded in python, so it wont be as fast as native C++ code.

No Overlay | Blender Retopo Overlay | DrawXray Overlay

How to use:

  • Install DrawXray like any other Blender add-on - see Blender docs
  • In 3D View Top Bar > Viewport Overlays > 'Enable Xray' - if you go to mesh edit mode, you will se new overlay rendered on top of your mesh
  • Xray Overlay can be enabled in following modes: Edit, Sculpt, Paint, Object (Shift+Click to select multiple modes).
  • Paid version has Snapping section, where you can set snap target (All scene objects, single target or collection)

Paid version (extension) comes with custom snapping engine and retopo tool:

  • Xray snap engine takes into account mesh curvature: sink lowpoly mesh into valleys, push outside on peaks. See this YouTube video below for details
  • Xray will negate mesh shrinking effect caused by subdivision modifier (see same video above),
  • Quad stroke drawing feature (new in 4.0)
  • Strip Wrap around joints feature (new in 4.1)
  • paid version comes with built-in auto-updater (new in 4.0)


Note: I included fixed version of F2 add-on (mesh_f2_xray.py) - which wont crash when using F2 together with DrawXray. To use patched F2 addon: disable the build-in F2 version and replace it with fixed version (it is named 'F2 Xray Fix'). For your information, I provided patch to blender devs, with the fix, but it got ignored...

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)

  • Added compatibility with Blender 3.0

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