Having explored the fundamental role of modifiers, it’s important to delve into the specific Types of Modifiers and Their Functions to fully grasp their capabilities within Blender 3D.

Types of Modifiers and Their Functions


You can apply modifiers to meshes, curves, and text objects to achieve various effects without permanently altering the base geometry.

To use the modifier menu in the properties panel, it offers six distinct menus for adding modifiers

Geometry Nodes


The Geometry Nodes modifier is a single modifier, not a menu. It enables you to build custom modifiers or tools using the node system. Although it’s just one option, you can create endless functions from it. Write in English, please.

Edit Types

These are the least used modifier types and arguably the most advanced and focused of the various modifier types.

They are used to edit properties of the object that other modifiers do not effect. Examples of this include the Weighted Normals Modifier, which adjusts the influence of an objects normals direction.

Another example is the UV Project Modifier, which allows you to select UV maps from a list that you have created and switch between them on your model.

Generate Types

These are the most common form of modifiers used and their is always a high chance in Blender that when you create a mesh object you will use at least one modifier as a part of that workflow.

One common type of modifier is the Subdivision Surface Modifier, which smooths the geometry of an object by subdividing its faces. This is particularly useful for creating organic shapes and high-resolution models from simpler ones. On the other hand, the Boolean Modifier allows for the combination or subtraction of multiple mesh objects, enabling complex shapes to be created with relative ease.

Modifiers like the Array Modifier replicate an object along a path or in a specified pattern, which can be invaluable for creating complex scenes with repeating elements. The Mirror Modifier, meanwhile, mirrors an object across a specified axis, greatly simplifying the process of creating symmetrical models.

Deform Types

The generate modifiers control geometry amount, while the deform options alter geometry behavior, influenced by other objects.

In this section, several modifiers need you to map them to another object in your scene to determine their effect.

For animation and rigging, the Armature Modifier is essential as it deforms a mesh based on the position of bones in an armature. Similarly, the Shape Key Modifier is used to interpolate between different shapes, which is especially useful for facial expressions and other detailed animations.

Physics Modifiers

Modifiers in Blender also include utilities for simulation and effects. The Cloth Modifier simulates fabric physics, while the Particle System Modifier is used to generate things like hair, fur, or rain. The Fluid Simulation Modifier allows for the creation of realistic liquid behaviours.

Hair Modifiers

Finally we have the hair modifier type, which as you may have guessed allows us to create hair particle systems. We use the particles tab for hair, but these modifiers provide a modern, precise approach to applying hair to models.

For example we can use the Generation options such as the Generate hair curves to start creating the hair.

Then we can use Deformation options such as the Frizz hair curves to add variation and style to the hair.

Each modifier comes with a set of parameters that can be fine-tuned to achieve the desired effect. The stacking order affects the final result because each one applies to the object’s data in sequence. This stacking system provides a high degree of control over the modification process.

In the next section, we will explore How to Apply and Manage Modifiers in Blender, which includes understanding how to add, adjust, reorder, and remove modifiers to achieve the perfect result for your project.

The most popular type of modifier is the generate type. One of the easier ones to learn and use is the triangulate modifier (Learn More).

How to Apply and Manage Modifiers in Blender

To apply a modifier in Blender, first select the object you wish to modify.
First, go to the Properties panel’s right side, click the wrench icon on the Modifiers tab.

You can select modifiers by clicking “Add Modifier” in the dropdown menu to enhance your object in various ways.

Once a modifier is added, you can adjust its properties through the interactive fields and sliders that appear. These settings allow you to fine-tune the modifier’s influence on the object.

Note that these procedural tools apply in a top-down order. The first modifier in the stack affects the object first, followed by the second one.

Arrange The Stack

To manage the stack, Blender provides several options. You can reorder modifiers by clicking and dragging the modifier’s title bar up or down. To duplicate a modifier, click the duplicate button (two squares) next to the modifier’s name.
To permanently modify the geometry, click the dropdown arrow, select “apply.” But remember, this change is irreversible after saving and closing the file.
