Wireframe overlay material

In your harnessBlender toolMIT

Build a material that renders every polygon edge as a glowing line over a base surface, with the line width in pixels or metres and an optional fade on surfaces seen edge-on. Use it for technical renders, topology presentations, sci-fi looks and blueprint styles.

Render of Wireframe overlay material
The render its check recorded in Blender 5.2.1, 192 by 192 pixels.

Limits. Relies on the Wireframe shader node, which Cycles renders; EEVEE does not support it and shows the base surface only. Edges come from the triangulated render mesh, so n-gons show their internal triangulation. Lines are emissive and do not cast shadows. Rendered here with Cycles CPU only. Verified in Blender 5.2.1; written for the 4.2 API.
