@Finema : I have confirmation you have access at all libraries of anything, packs etc...!
Users of Blender can use it directly with Bridge even Shaders, maps EXR etc...!
not by me:)
"We succeed when you succeed
Use for free, pay 5% when you ship" https://www.unrealengine.com/en-US/faq
"Get Unreal Engine 4 here, and with one free download access all engine features" etc...
I suggest you to load the free TwinMotion https://www.unrealengine.com/en-US/twinmotion
Like this the Epic Launcher will be installed too by default
Then you must be have no problem !
I have a friend who has that!
You can use the FBX format for import the assets ( 10 700 Hight Quality) inside Twinmotion !
Then use the Textures from Quixel inside TwinMotion
Unreal Engine 4.24 to ship with free Quixel Megascans, Unreal Studio features, and more
Quixel Megascans free for all use with Unreal Engine
Quixel, creator of the world’s largest photogrammetry 2D and 3D asset library, has joined the Epic Games family, and we’re making the entire Quixel Megascans library of more than 10,000 high-quality, production-ready assets free for all use with Unreal Engine!
At each time (session) on quixel.com !!! Yes that the trick!
Sign Out - Sign in with Epic Game Launcher (first top choice ...so no need Mail / Password for Quixel...it's the Epic Launcher who makes that)
and you have not the screen that you show and then choice Menu Products / Browse Megascans
then download all that you want! :)
And of course maybe texturize any Moi Object! ;)
You can choice FBX or OBJ, size image 2K to 8K etc...
for example here the asset 3D with only its texture in Simlab :)
You can also download these 2 free things ! Bridge (for export to third party) and Mixer for make texture "with zero learning curve! :)
