This is HAL Archviz Toolkit v1 from Unreal Engine Marketplace. I bought this two weeks ago and this is the content data of toolkit's default project. I don't change anything.
If you want to use it with your project, you should migrate the toolkit's project's content with "your" project's content.
Instructions.
1- Open this project
2- In asset browser, right click HALToolkit root folder
3- You will see a new windows. Choose root folder again
4- After this, you should browser your project's content folder.
5- Use it !
