Creating Surface Patterns with Blender Noise Texture and Voronoi Texture

What you’ll learn in this guide

Blender’s Noise Texture and Voronoi Texture nodes offer two distinct ways to create procedural surface patterns. Noise Texture can evaluate Perlin noise on its own or combine different layers of detail. Voronoi Texture calculates distance, color, and position information related to feature points and the cells they form.

In this guide, you’ll first identify which node suits the pattern you’re after, then explore the basic settings in a controlled way. We’ll also look at why noise may produce similar values in some scenes, and what changes you can try if you see banding or render artifacts. The examples aren’t specific material recipes; they’re workflows for comparing the effects of different settings.

Requirements and preparation

You’ll need Blender. The reference material is the current Noise Texture and Voronoi Texture documentation in the Blender Manual. These pages don’t specify a version number, computing requirements, or any additional add-ons. Check that the nodes and options covered here are available in the version of Blender you’re using.

Before you start, decide what kind of result you want on the surface: more uniform noise, sharp ridges, or cell boundaries and distance information. This will help you choose a node. In both nodes, if the Vector input is left unconnected, Generated texture coordinates are used by default. Both nodes offer 1D, 2D, 3D, and 4D evaluation dimensions. Since higher dimensions can increase render time, it makes sense to avoid dimensions you don’t need.

Step by step: Working with Noise Texture

1. Check the Scale value. Scale in Noise Texture determines the scale of the base noise octave. For your first test, keep the other settings fixed and change only Scale. This makes it easier to see how the pattern distribution changes.

2. Choose the Detail level. Detail sets the number of noise octaves and can take a fractional value. For example, a value of 2.5 blends 2 and 3 octaves by 50 percent. Compare the surface result to determine how much detail you need; the source doesn’t state that the number of octaves in Noise Texture increases evaluation time.

3. Compare the Noise Type options. The Type setting changes how octaves are combined. In fBM, octave values are added, producing a result described as homogeneous and isotropic. Multifractal multiplies the values; the source describes this as a result that varies with position. Hybrid Multifractal combines addition and multiplication. Ridged Multifractal produces sharp ridges. Hetero Terrain is associated with terrain forms resembling river channels. Use these options to explore different noise behaviors.

4. Test the inputs that change the pattern’s character, one at a time. Roughness affects the transition between a softer pattern and sharp peaks. Lacunarity determines the scale difference between successive octaves. Offset is an added shift to the octaves, while Gain is an additional multiplier that adjusts their magnitude. Distortion controls the amount of distortion. Change just one input in each test so you can interpret the result.

5. Check the dimension and normalization. The 1D option uses the W input; 2D and 3D evaluate the Vector input. In 2D, the Z component is ignored. In 4D evaluation, W is added to Vector. Bear in mind that higher dimensions may increase render time. The Normalize option keeps fBM output within the 0.0–1.0 range; when it’s disabled, the value range depends on settings such as Detail and Roughness.

Step by step: Cell patterns with Voronoi Texture

1. Choose a Feature option for your purpose. F1 provides distance, position, and color information related to the nearest feature point. F2 calculates the same information for the second-nearest point. Smooth F1 is a smoothed version of F1. Distance to Edge calculates the distance to cell edges, while N-Sphere Radius calculates the radius of n-spheres placed in the cells.

2. Compare the distance metrics. The node offers Euclidean, Manhattan, Chebychev, and Minkowski options. Minkowski generalizes different distance metrics using an exponent parameter: an exponent of 1 is equivalent to Manhattan, while an exponent of 2 is equivalent to Euclidean. An infinite exponent corresponds to Chebychev. Keep the coordinates and other settings fixed while comparing them.

3. Try different Randomness and Smoothness values. Randomness controls how random the pattern is, while Smoothness adjusts its smoothness. When using Minkowski, Exponent sets the exponent value for the distance calculation. Change the parameters one at a time to observe how the cell structure changes. When Normalize is enabled, values are kept within the 0.0–1.0 range; the manual notes that they may rarely fall outside this range when F2 is selected.

4. Evaluate the outputs separately. Voronoi Texture provides Distance, Color, Position, W, and Radius outputs. The cell colors in the Color output are arbitrary; don’t interpret them as a specific physical color standard. Selecting an output based on the information you need and examining its effect on the surface helps you understand the node’s role.

Common issues

Noise Texture may produce similar values instead of the expected variation with certain coordinate arrangements. In the example given in the manual, objects in a grid are positioned at whole numbers, and noise can become fixed at a value of 0.5 under a particular scale arrangement. Options to try include changing the scale, adding an arbitrary offset to the texture coordinates, or evaluating in a higher dimension and adjusting the additional dimension. In some cases, using White Noise Texture may also be preferable.

Banding can also occur on flat or gently sloping surfaces. The Blender Manual explains that when coordinates change slowly along one axis, the grid structure of the noise can become more visible. Rotating the coordinates by an arbitrary amount is one recommended way to reduce this issue.

Render artifacts can occur with Voronoi Texture, especially when Randomness is low. Keep this possibility in mind when checking the result. Also note that increasing the dimension in either node can increase render time. Since the source gives no warning about the effect of octave count on evaluation time for Noise Texture, don’t assume there’s a render-time impact from this setting in that node.

Impact on architectural and visualization workflows

Noise Texture gives architects, interior designers, and visualization artists a way to explore different types of noise. Voronoi Texture, in turn, lets them work with cell, distance, and position information. Students can compare the effects of changing parameters one at a time, while visualization teams can test and select the node that best suits the surface character they’re after.

To avoid unnecessary complexity in production scenes, don’t use evaluation dimensions you don’t need, and test render times. The sources don’t specify particular hardware requirements, a Blender version number, or different licensing terms. Check the options in the version you’re using and the licensing terms of your project separately.

Next steps

Test the same surface first with Noise Texture, then with Voronoi Texture. Change one setting per pass and record how it affects the pattern. If the Noise pattern shows a constant value, test the scale and coordinate offset separately; if there’s banding, test coordinate rotation. For Voronoi, first choose the Feature and distance metric, then compare the Randomness and Smoothness settings.
