Emitter effect in blender 3d is one of the feature that you can use to help give fluorescent lighting to surrounding objects. I’m sure you see a lot of this Blender 3D Tutorial: Light It Up with Fluorescent Effect [Neon] in science fiction movie. From this practice we also will learning about Backface Culling ( next post ) where only the inside of the object is visible. After finish this tutorial I think you can apply it on cafe and booth interior design.

Okay, let’s start then…

1. Make a plane as your floor and one object, anykind of object that we will add fluorescent effect. I choose to type my social media username, svnserendipity.

2. Select your object and create a new material. Choose diffuse color you want and on shading increase the emitter value to 2. On world slot, check Indirect Lighting box and on Gather choose Approximate. Try to render your scene. Below are the details instruction and my test render.

Save Selection with Vertex Group in Blender 3D.

At this point I think it’s enough for beginner to know the basic of this fluorescent lighting. It’s easy, right?. But what if you want to add 2 material on one object that only have 1 material with emitter value increase?. Of course you can do that by selecting faces you need with vertex group technique. This is just one of the way for a quick work.

I’m gonna add a sphere object, enter edit mode, and select certain faces for each material you plan to add.

For my sphere above I will saving faces in material 1 using vertex groups. Make sure the material 1 is selected, go to object data slot, on vertex group click + sign, rename group, and click assign button. Try to click select and deselect button see if it’s working.

How to Add 2 Materials in One Object in Blender:

First we will add a base color for material. Create a new material and choose blue on diffuse color. Now go to object data and choose material 1 on vertex group list.

Again create a new material, choose yellow color, and change the emitter value to 2. Now, we have 2 color material in 1 object, like mine below:

Try to render it. It’s pretty cool, huh?.

As a simple person myself, I like this effect. You can use it if you want to type quote, apply it on single object, or make one object outstanding among others. I’m sure a lot of interior designer will find this feature delightful.

On next second part tutorial of this project, we will learning how to add this 2 object on a neon room or in this case inside a cube. Stay tune and subscribe so you don’t miss my update. As always, thank you for reading!.
