What is 3D Noise Texture and Why You Need It
Definition of 3D noise texture
A 3D noise texture is a type of procedural texture that generates random values in three dimensions. Unlike a regular 2D image, a 3D noise texture has depth and can represent the internal structure or variation of a material. For example, a 3D noise texture can simulate the grain of wood, the veins of marble, or the clouds in the sky.

How to Create Your Own 3D Noise Texture in Blender
Steps to create a 3D noise texture in Blender
If you want to have more control and creativity over your 3D noise texture, you can create your own in Blender. Here are the steps to do so:
Open Blender and create a new file.
Add a cube object by pressing Shift + A and choosing Mesh > Cube.
Select the cube and go to the Shading workspace.
In the Shader Editor window, add a Noise Texture node by pressing Shift + A and choosing Texture > Noise Texture.
Connect the Color output of the Noise Texture node to the Base Color input of the Principled BSDF node.
Adjust the Scale, Detail, Distortion, and Roughness values of the Noise Texture node to change the appearance of the noise.
If you want to make the noise 3D, add a Texture Coordinate node by pressing Shift + A and choosing Input > Texture Coordinate.
Connect the Object output of the Texture Coordinate node to the Vector input of the Noise Texture node.
To animate the noise, add a Mapping node by pressing Shift + A and choosing Vector > Mapping.
Connect the Object output of the Texture Coordinate node to the Vector input of the Mapping node.
Connect the Vector output of the Mapping node to the Vector input of the Noise Texture node.
Increase the Z value of the Location property of the Mapping node over time by inserting keyframes.
To export your 3D noise texture as an image file, go to the Image Editor window and choose Image > Save As.
Conclusion and FAQs
In this article, we have learned what 3D noise texture is, why you need it, and how you can find and download it online. We have also shown you how you can create your own 3D noise texture in Blender, a free and open-source 3D creation software. We hope that this article has helped you to understand and use 3D noise texture for your 3D projects. If you have any questions or comments, feel free to leave them below. Here are some FAQs that might be useful for you:
What is the difference between 2D and 3D noise texture?
A 2D noise texture is a type of procedural texture that generates random values in two dimensions. It can be used to create surface patterns or variations on a 2D plane. A 3D noise texture is a type of procedural texture that generates random values in three dimensions. It can be used to create internal structure or variation of a material in 3D space.
What are some types of 3D noise texture?
There are many types of 3D noise texture, each with different characteristics and applications. Some common types are:
Perlin noise: A smooth and continuous noise that can create natural-looking textures.
Voronoi noise: A cellular noise that can create irregular shapes and patterns.
Simplex noise: A faster and less grid-aligned version of Perlin noise.
Worley noise: A variant of Voronoi noise that can create more organic and realistic textures.
Fractal noise: A combination of multiple layers of noise with different frequencies and amplitudes.
How can I use 3D noise texture in other software or game engines?
If you want to use 3D noise texture in other software or game engines, you need to export it as an image file or a volume file. An image file is a 2D representation of the 3D noise texture, which can be used as a texture map for materials or shaders. A volume file is a 3D representation of the 3D noise texture, which can be used as a volumetric data for rendering or simulation. You can export your 3D noise texture from Blender as an image file or a volume file by following these steps:
Select the object that has the 3D noise texture applied.
Go to the Render Properties panel and set the Render Engine to Cycles.
Go to the Output Properties panel and set the File Format to PNG for image file or OpenVDB for volume file.
Go to the View Layer Properties panel and enable the Data passes for Material Index, UV, Normal, Vector, Z, Mist, Emit, Ambient Occlusion, Environment, Shadow, Diffuse, Glossy, Transmission, Subsurface Scattering, Volume Direct, Volume Indirect, Cryptomatte Object, Cryptomatte Material.
Go to the Compositing workspace and add a File Output node by pressing Shift + A and choosing Output > File Output.
Connect the outputs of the Render Layers node to the inputs of the File Output node.
In the File Output node properties, set the Base Path to where you want to save your file.
Go to the Render menu and choose Render Image.
How can I improve the quality of my 3D noise texture?
If you want to improve the quality of your 3D noise texture, you can try some of these tips:
Increase the resolution of your image or volume file when exporting from Blender.
Increase the Scale value of your Noise Texture node in Blender to add more detail.
Increase the Detail value of your Noise Texture node in Blender to add more contrast.
Increase the Distortion value of your Noise Texture node in Blender to add more variation.
Mix different types of Noise Texture nodes in Blender using Mix RGB nodes or Math nodes.
Add some color or gradient to your Noise Texture node using Color Ramp nodes or Gradient Texture nodes.
Where can I learn more about 3D noise texture?
If you want to learn more about 3D noise texture, you can check out some of these resources:
: A chapter from an online book that explains the theory and practice of using noise in shaders.
: A book that covers the principles and techniques of procedural texturing and modeling, including noise generation and application.
