- Easy tutorial on procedural materials in Blender, for creating an animated nebula using the noise texture node. This short tutorial uses nodes to create and animate a procedural nebula texture that is perfect for abstract and scifi visual effects (VFX). Using the Eevee render engine, it is extremely render friendly, enabling high quality visual effects (VFX) and animations. For the animation, Blender's drivers are used in a simple way. This straight to the point tutorial shows every step of the material creation and animation process, with information helpful for both beginners and advanced shader artists and 3D modelers. It demonstrates the use of many of Blender's shader nodes (especially, noise texture node), as well as a simple driver.
Nebular backdrops can give scifi environments a beautiful look, and are an effective way to make a 3D scene more interesting. In this tutorial, I show you how to use Blender's shader nodes to generate a procedural nebula texture effect that can be applied to any 3D model.

đ Summary:
Whether you want to add a backdrop to you a scifi scene, or if you want to create a vibrant background for your computer desktop, this tutorial, will show you an easy method to create a proceduraly generated nebular texture, and a simple way to animate it, using Blenderâs shader nodes.
So, lets fire up Blender. As you can see, we are starting off with a camera, pointing at a simple plane. Lets also point out, that we are using the Eevee render engine, with the sample, set to 1. Meaning that the result, will be extremely render-friendly. Now, lets head over, to the shading viewport. By default, when we create a new material, Blender gives us the principled BSDF shader, which has many parameters. However, here, we will only be using the Emission color, Emission strength and Alpha channel of this shader. To start, lets create the main branch of our shader. So, use the add menu and search for, a Texture Coordinate node. Followed by a Mapping node, a Noise Texture node, and a Color Ramp node. Here, we will be using the Object output of the Texture Coordinate node. Also, make sure to set the Noise Texture to 4D. The Color Ramp node, will determine, the density of the Nebula, through the Alpha channel of Blenderâs Principled shader. However, to get the alpha channel to work properly, we need to go to the material properties, and set the blend mode, to, alpha blend.
Now, to add some detail to the texture, add another Noise Texture Node, along with a, mix RGB node. The combination of these two nodes will enable us to add some noise, to the input coordinates. As you can see, we can adjust the intensity of the added noise, using the, mix RGB factor.
Next, to add some color, and lighting, to the nebula texture, lets add another color ramp node, and a math node. Both of these nodes, will take their input from the preceding color ramp node. Go ahead and attach the new color ramp node, to the emission color of the principled shader.
Now, to animate the texture, we are going to use a simple, Blender driver. So, lets add, a Value node, along with a Vector math node, and a simple Math node. To set the driver, select the value node, enter a pound sign, and type in âframeâ. During animations, this value, will give us the current frame number, which, we can then use to drive other parameters. So, connect this driver value to the Vector math node, to offset the X value of the texture coordinates. Make sure to set the Vector math node to divide the input values. Then, again, use the driver value, this time, by attaching it, to the math node. This will make the noise texture, change, over time. Again, make sure to set the math node, to divide, the input values. Now lets play the animation, by hitting spacebar, on our keyboard. If the texture is moving too fast, or too slow, you can use the parameters of the math nodes, to adjust the speed, of the animation.

Animated texture! So awesome....
I love the video, helped me out a lot! Also the editing is really relaxing ngl
Glad it helped!
Thank you. It helps me to make waves using Musgrave texture
Best tutorial that i've seen about this, keep the great job!
Thanks, will do!
Very good video, just what i was searching for! :)
Glad you liked it!
Many thanks man. This was a great help.
Glad it helped
Great video, very helpful!
Glad it was helpful! :)
i love u, ty so much
Thanks a lot! I've looking for how to animate the W value of the Noise Texture.
I made this for an explosion texture, then duplicated the material for the smoke clouds but its not animating for some reason even though its exactly like the fire clodus texture except for some adjustments to make it look like smoke.
Which settings/ what steps should i follow if i wanted to go for a more static or electric kind of look?
Can the simulation be triggered with a sound track instead of frame number Thanks
Anyone know how to do this for Unity? I need to make an infinite scrolling background with procedurally generated nebulae đ€
WHAT ELSE IS THERE BESIDES #FRAME...because i can #frame even a texture, i just want t o know if there are other hashtag commands for different nodes and if there is any literature or resouces about this. I CANNOT find relevan information anywhere on the internet
How do I save this as a video ????????
how add an ADD NODE ?
search for "vector math" and you will find it
