Long has the prophecy foretold of the day Poly Haven makes their assets available directly in Blender.
Today is that day!
Here's a little demo of it in action:

Download it at the bottom of this post.
This add-on is for sale on the Blender Market, in an effort to raise funds for us to create more assets, but we're also making it available to all $5+ patrons.
The add-on also includes early access to upcoming assets. Any time we upload a new asset, it’ll immediately be available to you inside Blender, sometimes months before we share it publicly on polyhaven.com.
Some usage documentation is available if you have any issues or need help installing/using the add-on.
Let me know what you think!
