How to Set Up an Emission Shader in Blender

Setting up an emission shader in Blender allows you to turn any object into a light source, perfect for creating neon lights, glowing screens, sci-fi elements, and lasers. This guide provides a straightforward walk-through on how to create and adjust emission materials using both the standard Principled BSDF node and the dedicated Emission shader node in Blender.

Method 1: Using the Principled BSDF Shader

The fastest way to add emission to a material is by using the default Principled BSDF node.

  1. Select the Object: Click on the 3D object you want to make glow.
  2. Add a Material: Go to the Material Properties tab (the red sphere icon on the right panel) and click New.
  3. Locate Emission Settings: In the material settings, scroll down until you see the Emission section.
  4. Set Emission Color: Click on the Emission Color field (default is black) and choose your desired color.
  5. Adjust Strength: Increase the Emission Strength value above 1.0. Higher values create a brighter light output.

Method 2: Using the Dedicated Emission Node

For cleaner node setups or complex shading networks, you can use the standalone Emission node in the Shader Editor.

  1. Open the Shader Editor: Switch to the Shading workspace at the top of the screen, or split a window and set it to Shader Editor.
  2. Add the Emission Node: Press Shift + A, go to Shader, and select Emission.
  3. Connect to Output: Drag the green Emission output plug and connect it to the Surface input of the Material Output node. (You can select and delete the default Principled BSDF node by pressing X).
  4. Configure Light Settings: Set your preferred light color in the Color box and adjust the brightness using the Strength field.

How to Make the Glow Visible in Render Engine

How your emission material interacts with the scene depends on the active render engine:

  • Cycles: Emission shaders automatically cast actual light onto surrounding objects without additional setup.
  • Eevee: To get a visible glow effect around the emitting object, go to the Render Properties tab (the camera icon) and check the box for Bloom. To make the emission cast light on nearby surfaces in Eevee, enable Irradiance Volumes or use Raytracing (available in Blender 4.2+).
