Neon tube material with a glass sheath
In your harnessBlender toolMIT
Build a neon sign material: an emissive gas core, whitened at the face-on centre, mixed by the Fresnel term with a clear glass sheath that takes over toward the silhouette. Use it for signs, cyberpunk scenes, bars and stylized lighting.
What it takes and gives
- Operator
- baltor.material_neon_emission
- Parameters
- material_name, color, strength, core_whiteness, sheath, assign
- Result
- One emissive material with a node tree; assigned to the active object.
- Blender
- 4.2 or later
- Axes
- Blender Z up, -Y forward
- Units

Limits. Emission lights the scene only in renderers that treat emissive meshes as lights (Cycles does, with noise); EEVEE needs light probes or extra lamps. No bloom: add glare in the compositor. The white core is a stylized ramp, not a gas discharge spectrum. Rendered here with Cycles CPU only. Verified in Blender 5.2.1; written for the 4.2 API.
