Hello everyone and welcome to another Blender 3D tutorial! In this video, we'll be exploring the Geometry Nodes and creating a simple glass cube animation with tiny emission elements.
First, we need to open Blender version 3.4 and delete the light and camera as we don't need them for this project. Then we'll click on the Cube and go to Geometry Nodes to add a new line.
Our first block will be to distribute some points on faces. To do this, we'll click shift plus a and on the search menu type "distribute points on faces". By default, it's set to 10 density, but we'll increase it to around 90 for better results.
Next, we'll take instance on points as our second block, but everything disappears because Blender doesn't know what we want as an instance. So we'll create a cube as an instance by dragging the green point to the left and typing "Cube". To reduce the size of our cube, we'll set it to 0.1.
Then we'll add some kale instances block and drag the scale properties to the left. We'll search for float curve to scale our instances in an interesting way by dragging a waveformed shape. We'll pick a position for the first value and be sure to check the clamp box.
To animate our instances, we'll take the value of the math node and put it on the scale properties of our instance on points block. We'll set keyframes for our animation by going to the first frame, giving it a value of -1, pressing I to insert a keyframe, going to frame 125, changing the value to 1.8, pressing I to add another keyframe, and keeping this keyframe at 1.8 until frame 1440.
To smooth out the animation, we'll set the final keyframe back to -1 and press I to set the final keyframe. By pressing the space button, we can play the animation.
Next, we'll set some materials. We'll pick our default Cube and set the material to glass with roughness on 0.1. We'll create a plane, turn to render mode, and create a new emission material with a strength of 5 points and a light blue color.
On the geometry nodes, we can set material, pick material zero one, and drag it between the cube note and the instance note. This will make our instances glow with the emission material.
To make our glass cube visible, we'll add a joint geometry node and drag the group input, which are the default glass cube, to the joint geometry. As we play the animation, we can see the whole emissions inside our glass cube.
That's it for this short and simple animation. If you have any advice on a better way to use Geometry Nodes, please let us know in the comments below. Thanks for reading!
