To create the bloom effect that emissive materials generate, go to the render tab in the properties panel and enable the setting for bloom. This is true for both emission and transparency. While Cycles is designed to create realistic scenes using ray-traced methods, Eevee uses more traditional rasterized methods of faking realism. The first step is to prep your Eevee engine work with both transparency and emission.

How To Set Up Transparency In The Eevee Render Engine? Like any material you can use any number of node combinations to create your desired effect, but the foundation of those three shader nodes is important to create that hologram appearance. You will also need to change the blend mode of the material to Alpha Hashed to view transparency in Eevee. Use the Fresnel node as the factor for the two attributes to create the hologram look. To create a hologram material in Eevee, delete the principled shader for your material and replace it with a mix of transparent and emission shaders. A very popular material to learn that is also a great exercise is to create a hologram material, which applies several key material attributes, like emission and transparency. The ability to create realistic materials using the Eevee render engine is a little more challenging than in the Cycles engine, considering Eevee is primarily built for speed.
