Python Script: Set Up a Wire Render


This Python script will help you make clay and wire renders.

liero writes:

A script to setup and apply materials for a wire render... It will replace your own with a clay and a wire materials, as seen here and here.

You can apply settings to all visible or just selected MESHES. Anyway, it's very easy to use.

  • works in BI on meshes only
  • by default it will run over all visible objects, but you can restrict to a selection
  • script looks for materials by name: rename or make single user to get different wire colors
  • 'mat_wire' has a z-offset option than can be used to fine tune wires display
  • enable ambient occlusion or 'shadeless' option to do a fast render without setting up lights
  • if it fails in default mode try selecting objects and enabling 'selected meshes'

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. Thanks for that !
    In the future, another way which don't use z offset could be better, but this add-on is great.
    Thanks again !

  2. Since this is a very commonly used rendering style... wouldn't it be useful to have it as a basic render option? I. e. a "render as clay" or "render as wireframe" button, that leaves your scene as is.

  3. really really usefull, I havent watched yet what you did to "upgrade" the old way but this is faster, I like it ! thanks
