Installation

Blender 4.2 introduced extensions. Extensions are .zip files that you can download online or get from an extension repository within Blender. More information is available on the official Blender extensions website.

Install From Disk

Paid addons (memsaver, renderset, ...) are installable from disk. First, download the .zip file from Superhive, Gumroad and install it from disk into Blender.

Remote repository

We plan to have all extensions available online, but for now only the open-source versions have a remote repository. Follow our Discord for updates.

This documentation showcases the installation process on engon, but it works the same way for other extensions.

Remove old addons

Before installing a newer version of addon extension, Uninstall all the previous versions of the addon in Blender. Having multiple different versions can cause issues and the addon extension might not work correctly.

Drag & drop the ZIP to install

You can just grab the downloaded .zip file and drop it into Blender to install it.

Once you have the .zip file downloaded, open Blender Preferences and go into the Get Extensions section. Expand the dropdown in the top right corner and click Install From Disk....

This will open a File Browser. Find the .zip file that you already downloaded, select it and click Install From Disk.

Once the installation is successful, the extension will appear in the extensions list.

You can find the preferences of the installed extension in the Add-ons section. Type the engon into the search bar to find it quickly.

Remote Extension Repository

We host remote extensions repository for our free addons. You can setup the repository in following steps.

Requires online access

Using the remote repository requires online access to install and update the addons. To enable online access, open Preferences, click System and in the Network panel toggle the Allow Online Access.

Open Preferences and navigate to the Get Extensions section and click Repositories in the top right corner.

Inside Repositories click the + button and select Add Remote Repository.

Copy https://extensions.polygoniq.com/api/v1/extensions into the URL and click Create.

Check for updates on startup

Toggle Check for Updates on Startup to automatically detect new updates if available.

Custom directory

By default Blender will install the extensions in User Directory. You can install to a custom directory by enabling the Custom Directory checkbox and selecting a folder.

This will create polygoniq.extensions.com extension repository and you should see a list of available polygoniq extensions in the extension list. If you have the official blender extensions repository enabled, our extensions will appear after it (at bottom of the list). You can always toggle what's visible in the Repositories popover.

Updating

engon contains automatic updating functionality. Updater is located in the engon preferences under the Updater Settings. You can check for updates by clicking Check now for engon update or tweak the updater settings. By default the updater checks weekly whether there is a new update, you can tweak this interval by changing Interval Between Checks.

engon connects to the internet

To figure out the newest version engon connects to the internet and checks against the public engon repository. If a new update is available it downloads it from there.

Restart Blender to complete update

After successful update, engon will prompt you to restart Blender to complete the update process. This cleans the Python module caches and prevents version compatibility issues.

Auto updating can be turned off

If you don't want to use auto updating functionality, you can always download the newest .zip file from one of the sources and install manually. Don't forget to deselect the Auto-check for Update in engon preferences.

Addon installation conflicts

Having duplicate or outdated polygoniq addons can cause a variety of issues. We suggest to have newest versions when possible.

Symptoms of conflicting addon installations

• Buttons not doing anything
• Panels partially missing
• Preferences interface not being loaded correctly
• User preferences being lost between blender runs
• Question mark icons in engon browser

Why is it an issue?

Addons register code features (buttons, panels, ...) into Blender. Those features have a unique name in Blender application, if two addons use the same feature (e. g. two versions of engon) then there will be conflicts.

Additionally we ship shared libraries with our addons. We encapsulated them into each addon in the meantime, but some old versions don't do any encapsulation (make the library available globally), so other addons will use the global library, instead of their own.

Addons will report Conflicting Addons Found in their main panel and in preferences with two types of messages:

1. Old polygoniq addon found, ..., please migrate to engon and paqs.
2. Another installation of addon found (duplicate installation).

Error is still present even after solving the issue

Error report is updated only once per while. So wait for a ~minute and it will disappear. If not, we suggest to restart Blender.

Old polygoniq addon

Ideally you want to use newest versions of our addons, as we test their compatibility and can guarantee it long term. These old addon installations are no longer compatible if you install newer products like memsaver, engon, renderset, ..., due to changes in Blender API and so we could move forward and bring you better centralized user experience.

No longer compatible addons that should be uninstalled and replaced with their new counterparts are:

• megaddon
• aquatiq
• botaniq
• botaniq_evermotion_am154
• botaniq_evermotion_am176
• traffiq
• materialiq

Uninstall old conflicting addons

Error report mentioned in the first section will give you information about what conflicting addons were found. Go through all of them and uninstall them one by one. 1. Go to Edit -> Preferences and into the Addon section (Extensions if the addon is installed as extension in Blender 4.2) 2. Navigate to the Search Bar and search for the addons based on error message (or one by one based on the list). 3. Uninstall the addon 4. After all old conflicting addons were uninstalled Save Preferences and Restart Blender.

How do I update my asset addon?

Since early 2024 we transitioned old asset pack addons (botaniq including botaniq_evermotions, aquatiq, materialiq, traffiq) to addon manager engon and .paq asset packs. You can read more about the engon and asset packs in the documentation.

The process is now easier, you install only one addon, and manage your polygoniq asset packs inside from one place. Including tools for migrating when asset's are changed and with powerful browser.

I only use memsaver and renderset, do I need to update?

Preferably yes, as fore-mentioned, we guarantee compatibility of the newest versions. There is no need to be afraid, we always keep our addons backward compatible - your data from old versions won't be lost and will work in the newer version.

Duplicate installation of addon

Blender allows you to install multiple versions of the same addons. This can create conflicts of the versions overriding themselves. It is suggested to keep only the newest version of the addon.

Keep only the latest version installed

1. Go to Edit -> Preferences and into the Addon section (Extensions if the addon is installed as extension in Blender 4.2)
2. Navigate to the Search Bar and enter the engon.
3. Optionally collapse the preferences to make the view compact and uninstall all versions of the addon except the latest.
4. Save Preferences and restart Blender.

Blender 4.2 repositories

Only one addon extension should be enabled across all repositories at once. Having multiple repositories with different addons is possible, but we recommend using only one addon at once. Otherwise only the addon that's registered the latest into Blender (e. g. based on what addon repository is last in the list) gets its functionality registered.
