How to Smooth and Randomize in Blender

Updated on: November 30, 2022

Alright! You've created excellent models and learned to smooth or shape them the way you need them. However, two tools will optimize the finishing and detailing of your models and, on the other hand, will help you to understand how to transform their shape to become as crazy as you want. So, let's learn how to Smooth and Randomize in Blender.


You can find it in the left-hand side toolbar right down the Spin Tool, and once you click on it you will see a yellow manipulator in your mesh.

The Smooth Tool will look at all points you have selected and try to average their values in such a way as to smooth those angles. Then, when clicking and dragging, the yellow dot manipulator will try to interpret how to transform the arches based on the direction you’re dragging your mouse.

Note: Pull it out the figure becomes sharp; if you pull it in, then you smooth.

After performing the operation, you can go to the bottom left-hand of your screen, where you’ll see the Smooth Menu to find some options to control the settings. First, you have the “Smoothing” option, which is the numerical and exact method to smooth the model, just like the yellow dot manipulator. Then, you will see the “Repeat” option, which is how you can tell Blender how many times to repeat the level of smoothing by increasing the steps by clicking on the arrows. And finally, you can select or disable the axes where you can see the smoothness.

You can find it in the toolbar and get a little menu pop-up out by selecting and holding the smooth icon. Notice that the Randomize icon is like a distorted version of the Smooth Tool graphic representation.

At first, it seems that this tool doesn’t do anything. However, once you pull the yellow dot manipulator out, you’ll observe how extremely randomized the points on your Mesh are.

You may have wondered why you ever want to use this tool. Well, creativity can sometimes get weird, but you can find some practical and traditional uses. A very good example might be a ground plane (which with this tool is a quicker way to create grass), or you can use it to simulate some texture even when working in Solid Mode.
