Works in Blender v2.8 onwards.

How to Install and Use the Addon

Installation:

  1. Download the .zip file. (DO NOT extract the zip file)

  2. In Blender, navigate to Edit -> Preferences. Then the Addons tab.

  3. Hit the install button, locate the zip and install the zip file.

  4. Make sure the addon is displayed in the list and enabled (search for "Poliigon" if needed)

  5. In the 3D viewport, press ‘N’ to open the side panel in the viewport

  6. Click on the Poliigon Addon tab.

How to uninstall

  1. In blender, Edit -> Preferences. Then the Addons tab.

  2. Search for Poliigon

  3. Expand the Poliigon Addon item, and press the "Remove" button

    1. Alternatively, you can simply uncheck the box next to the addon name. This will only disable the addon, not uninstall it, making it easier to start using again later.

  4. For full cleanup, you can delete your ~homuser~/Poliigon/ folder - be aware that the default Library folder is ~home_user/Poliigon/Library so you may want to move or save the Library folder if you choose to uninstall and not lose your local assets.

Indepth How-To:

Background

Navigating the Addon

Section Buttons

The addon’s UI is separated into sections, listed below from left to right.

  • Poliigon Assets (Whole Library)

  • Show My Assets (Owned Assets)

  • Show Imported Assets (Assets currently loaded into the scene.)

  • Account Details (Account-related Settings)

  • Addon Preferences (Shortcut to the addon in User Preferences)

Poliigon Assets Section

Searching

The search bar allows you to refine the search by category (e.g. Textures, Models) and subcategories (e.g. Bricks, Modern). Initially, it will only show one button, then more will be added as subcategories become available.

The results displayed will be identical to the website.

Asset Boxes

The buttons underneath each asset will change depending on whether or not the asset is purchased and downloaded.

Unpurchased

  • Eye Icon - This Quick Preview allows you to apply a low-resolution, watermarked preview to the selected object. (Only applicable for materials currently)

  • Download - This will download the asset at the default* resolution.

  • Down Arrow - This Quick Menu allows you to view a larger thumbnail and quickly open the asset online.

* Default settings can be changed in the addon settings menu.

Purchased

  • Download - If purchased but currently not downloaded, this button will download the asset to your Addon library folder.

  • Import/Apply - Will import the downloaded asset into Blender, if an object is selected it will read as Apply, and will automatically apply the material to the selected object. If no object is selected, it will load the material into memory with a fake user but not apply it.

  • Down Arrow - This Quick Menu allows you Import/Download different resolutions of the asset.

Show my Assets Section

Same functionality as the main Poliigon Assets Section, however, results are limited to assets already purchased.

Show Imported Assets Section

Similar functionality to the main Poliigon Assets Section, however, results are limited to assets currently imported to Blender (Either applied to an object, or stored in memory via a fake user). This section not offer options to download or apply new resolutions.

Account Details Section

Adding Credits

  • Subscription Credits - Shows the current amount of credits from your Poliigon subscription

  • On-Demand Credits - Shows the current amount of on-demand credits.

  • Add Credits - This button will open your browser at the appropriate page to purchase additional on-demand credits.

Setting Subscription

  • Displays Subscription Details

  • Subscribe Now - This button will open your browser at the appropriate page to purchase/edit a subscription.

Settings Button

Shortcut to open the Edit -> Preferences -> Addon window.

Addon Preferences

To access the addon’s preferences navigate to the Edit -> Preferences -> Addons section, and then find the Poliigon addon. Or, click the cog icon in the Poliigon 3d view panel. Below are details of what each option does.

Library + additional directories section

  • Library - Main root folder for the addon to use when downloading assets

  • Additional Libraries - Allows you to specify additional directories to scan for download assets. (Note - Only Poliigon assets are supported currently.)

Display Preferences

  • Thumbnail size - Changes how large to make the thumbnails displayed in the 3D panel grid viewer

  • Assets Per Page - How many assets to show per page in the main UI.

    • Note: We suggest using a page size of 10 or smaller for the best stability

  • Refresh data - (v1.2+) Force a full refresh of icons and addon internal data, also available as a refresh icon in the 3D view panel next to the search bar

Asset Preferences

  • Textures:

    • Default Texture Resolution - The default resolution that materials will be downloaded in

  • Models:

    • Download + Import .blend Files - If checked, will download blend files instead of FBXs, does not affect LODs

    • Link .blend files - If a blend file is available and the preference to prefer importing is checked, will aim to link objects instead of appending

    • Default Model Resolution - The default resolution that model textures will be downloaded in.

    • Download Model LODs - If checked, automatically download all Level of Detail FBX files with the model

    • Default Model LOD - Which Level of Detail to import, if LODs are already local. If NONE is selected, the default blend file will be imported. Otherwise, the according LOD FBX file will be imported.

  • HDRs:

    • Default HDR Lighting Resolution - The default resolution for HDR lighting, separate from background resolution.

    • Use JPG for background - If checked, the default import operation will a different background resolution as specified below

    • Default HDR Background Resolution - The default background resolution for HDRs if "Use JPG for background" is enabled. This value will only effect the scene background, not lighting. It is a way to improve background resolution without loading the memory heavy lighting EXR at the same resolution, but will face more clipping issues and not respond to scene exposure as well.

  • Brushes:

    • Default Brush Resolution - The default resolution in which brushes will be downloaded.

  • Other:

    • Auto-Download - Toggle automatic asset downloading after a purchase.

    • Use Micro-displacements - Set Blender to Experimental mode and adds a subdivision modifier, and adds a non-zero default displacement value to materials imported (For adaptive subdivision, note: Displacement strength will still need to be adjusted in the material shader). Does not apply to models.

    • Use 16 bit maps: If they exist, load the higher bit depth maps such as for normal map improved accuracy

Other preferences

  • Auto-check for update (daily): Checks for updates once per 24h (if Blender is open). You can also always press "Check for update".

  • Verbose logging to console: Enabled by default, adds additional debugging information into the output system console. Does not affect addon behavior.

  • Share addon errors/usage: Also available at time of log in. If enabled, automatically shares errors encountered inside the addon to developers. Additionally will send key events inside the addon, such as pressing operators or viewing sections, so that we may better understand its usage and improve performance. We do not send any usage behavior outside the Poliigon Addon itself.

Using Materials

Applying a material

  1. Select the object you would like to apply a material to.

  2. Click the “Apply” button on the material selection within the addon.

Adjusting the imported material

To adjust the imported material, open the shading tab and locate the material node group.

Poliigon Nodegroup

  • Scale - Adjust the scale of the material.

  • Aspect Ration - Adjustment for non-square textures, will be adjusted automatically on import.

  • Translate X, Y - Move the texture along the X, Y access, corresponding to the UV.

  • Global Rotation - Rotate the material, corresponding to the UV.

  • Color Hue, Saturation, Value, Brightness, and Contrast Adj. - Adjustment sliders

  • AO Strength - Adjust the amount of influence the ambient occlusion texture has.

  • Roughness Adj. - Adjustment to the roughness map.

  • Normal Strength - Adjustment to the normal map’s strength.

  • Displacement Strength - Adjust displacement strength (Defaults to ZERO!)

  • Displacement Mid-Level - Adjust the mid-level of the displacement.

  • Bump Strength - Adjust the strength of the bump map (Defaults to 0.005)

  • Subsurface Multiplier - Adjust the effect of the SSS map.

* Certain values may be missing depending on the material imported. For example, if the material doesn’t have an SSS map, no Subsurface Multiplier value will be listed.

Using Models

Importing a model

  • Set the 3D Cursor to the desired location

  • Click Import within the addon

  • View the F9/redo last menu for more options on how to import, such as to import models as collections, or to change to link models instead of append (not applicable if importing LODs)

Model redo last settings

Right after importing a model, look to the bottom left of the 3D view or press F9 to pull up the "redo last" menu.

  • LOD - If any LODs are available, import that using the settings below. Not available if using "Link .blend file". LODs always load FBXs on disk, not the source blend file, so you may find there are some material setting differences.

  • Texture - Change the model texture to load, only will display already downloaded model resolutions

  • Import as collection - If ticked, create a collection for this model at the origin of the scene, and place an instance of that collection. Future model imports will continue to reference that existing collection instead of performing new imports.

  • Reuse materials: - If you have already imported this model before, reuse the prior material instead of creating a new duplicate

  • Link .blend file - If a blend file is available, live link the model. If disabled, all operations will act like "append"

Using HDRs

Importing an HDR will automatically assign it to the active world, or create a new one if necessary. You will not see this HDR unless you go into the rendered mode, and you can see the node layout in the shader window after switching to World. HDRs are imported with two image inputs, depending on your user preferences

  • Light - A higher-depth EXR file used to actually light the scene.

  • Background - The JPG image to be visible in the background render.

HDR redo last settings

Right after importing an HDR, look to the bottom left of the 3D view or press F9 to pull up the "redo last" menu.

  • Light Texture - The EXR resolution size which will be used to light the scene

  • Background Texture - By default will use the Light Texture, but you can select another typically higher resolution JPG

  • HDR Strength - How strongly the lighting texture will light up the scene

  • Z-Rotation - Rotate the whole HDR using this slider

Using Brushes

Importing a Brush

  • Select the object you would like to sculpt on

  • Click “Import”, this will enter Blender into sculpt mode and apply the downloaded brush with “View Plane” mapping and other appropriate defaults.

Other Information

  • We recommend you leave files and folder structures downloaded as-is without renaming, to avoid breaking connections with the addon

  • Remember to always restart blender after performing any updates of the addon

  • If you run into issues, you can chat with help on this page using the chat bubble to connect with our support team.
