In plain English

Poliigon Bridge is an unofficial plugin for Unreal Engine 5.4 and newer that adds an in-editor browser for Poliigon's library of 3D assets and materials. Instead of downloading files from the Poliigon website and importing them by hand, a user can search the library from inside the editor, click a Get button, and have the asset placed directly into the project's Content folder ready to use. Materials arrive as instances of a generated master material, and models arrive as static meshes with their materials already assigned. Signing in uses a person's normal Poliigon account through the website login, not a separate registration. The part of the plugin that talks to Poliigon's servers is a native port of the same client code found inside Poliigon's own Blender addon, which is released under the GPL license. Installing it means copying the PoliigonBridge folder into a project's Plugins directory, then opening the project and accepting a prompt to rebuild the module, which requires Visual Studio 2022 with the C++ game development workload installed. A rendering feature called Substrate then needs to be turned on in the project's rendering settings, followed by a restart. After that, the browser opens from a menu inside the editor and the user signs in with their Poliigon account. Free assets are marked as such and can be filtered with a dedicated checkbox, while paid assets draw from the credits on a person's existing Poliigon plan, the same way they would if downloaded from the website. Material instances expose a range of adjustable properties, including tint, roughness, normal strength, UV tiling and rotation, and displacement support for high detail rendering. HDRIs and brushes are not yet supported. The README notes that downloads should happen at a normal, human pace, since Poliigon applies its own fair use limits on the server side and this tool is meant as a bridge to an existing account, not a way to scrape or bulk download content. The project is licensed under GPL-2.0-or-later and is not affiliated with Poliigon.
