How to Install and Activate Add-Ons in Blender 3D

An Add-On (or plug-in) is a third-party tool to extend Blender’s functionality or simplify a workflow. Here’s everything you need to know about installing, activating and managing an add-on in Blender.

If you are looking for add-ons, here is my list of the best add-ons for Blender.

Blender Plug-In File Formats

Usually when we purchase or otherwise download an add-on for Blender, we get a .Zip file. You may occasionally run into other compressed file types.

Blender will be looking for a .Zip file so if you got a .Zip file do not unzip it! If you received another file format, you may have to decompress it and then compress it into a .Zip format.

Installing an Add-On in Blender

Here’s the step-by-step process to install and activate an add-on in Blender.

The preferences window will open. On the left side are several tabs. Select the tab labeled “Add-Ons.”

Step 2: Install Add-On from File

From the preferences window, click the “Install” button on the top right.

Navigate to the location on your computer where the stored .Zip file for the add-on is located. Select the file. Click Install Addon.

Step 3: Activate Add-On

In the preferences window, there is a long list of installed add-ons. Next to each add-on is a check box to activate and de-activate an the add-on.

At the top right of the add-on preferences is a search box. Type in the name of the add-on you just installed to find it in the list. Check on the box to the left of you add-on to activate it.

For most Blender add-ons, that’s all you need to do. Sometimes an add-on will have an additional set-up step…

Step 4: Add-On Settings

Some add-ons (not all) require additional set-up steps. To see what additional settings your add-on may have, click the arrow to the left of the add-on’s name in the preferences window.

Here we will see a description of the add-on, where the controls for it are located and other details. If the add-on has fields that need to be completed before it can be used, they will also be here.

As an example, the Poly Haven Asset Browser has the above settings which need to be configured before using it.

Here is the official Blender Manual documentation on add-ons.
