Hologram Effect in Blender (Short Tutorial) 

Holograms are a good way to give designs and logos a futuristic science fiction (scifi) aesthetics. This short tutorial shows how to create a hologram effect in Blender. This is done using shader nodes and compositing and can be applied to any 3D model to give it a futuristic scifi look. This short tutorial shows every step of the material creation process, with information helpful for both beginners and advanced 3D modelers. It demonstrates the use of many of the shader nodes.

🧐 Summary:
- Holograms are widely used in scifi movies and animations, as they are a good way of adding some lighting to otherwise dark scenes.
- Welcome another Blender tutorial, where I will be showing you how to create a hologram effect, using the cycles render engine.
- First off, switch to the Shader Viewport and delete the Principled BSDF shader.
- Then, add a Noise Texture node, a Math node and an Emission Shader node.
- This subset of nodes, will create some noisy lighting for the hologram.
- Now, add a Mix Shader node and a Transparent BSDF Shader node, along with a Texture Coordinate node, a Separate XYZ node and a Color Ramp node.
- This subset of nodes, will make the hologram lighting become more faint towards the top.
- Next step is to add another Mix Shader node, and an Emission Shader node, along with a Geometry node, a Layer Weight node and a Color Ramp node.
- This subset of nodes will give more depth to the hologram by lighting up the faces that are facing sideways from the camera.
- Now, add yet another Mix Shader node, this time, with a Bevel node, a Geometry node, a Vector Math node, a Color Ramp node and an Emission Shader node.
- Be sure to set the Vector Math node to calculate the “Dot Product” of the two inputs.
- This subset of nodes will highlight the edges of the hologram model and make it’s details more visible.
- Next, add another Mix Shader node, along with a Wave Texture node and a Transparent BSDF shader node.
- I would suggest selecting a dark color for the transparent shader node.
- This subset of nodes will make the hologram look as if being constructed by horizontal scan lines.
- Now, switch to the Compositor Viewport and select the “Use Nodes” option.
- Then, add a Viewer node and render your scene, using the shortcut F12, to see the post-processed background image.
- Then, add a Glare node and set it to “Fog Glow” to get a glowing effect around the hologram.
- And there you have it, a complete hologram effect that you can use to beautify and enrich your scifi scenes.
- I hope you have found this tutorial helpful.
