Wow it is shockingly bad
Have you tried downloading something from the FAB store yet?
Especially anything from Megascans?
I am seriously dumbfounded that this was released
Again I hate to be so negative
I am sure a lot of people worked hard but guys … this is just not good enough in any way frankly
So shocked at how bad it is
You need a functional workflow for customers to get the things they purchased into the project …
And no sift through a slew of zip and glib downloads to find what you want is not it.
Download to disk is a fine thing to have as an “extra nice to have” … however you do require at minimum an import to the project.
You are Epic so you should have ZERO issue doing this for UE
As to Unity, it’s not hard at all, Unity Package Manager can use Git URL to import a custom package if you want to be fancy there are 3rd party tools or you could even do your own in the editor (Bridge-like tool) really not hard to script for that editor at all
