Dude, you really seem confused.....

What is especially the case with Epic is that they don't allow specificaly to use content from their Unreal games, to name example, outside of their Unreal games, but using/porting the content across all the Unreal universe games they allowed.

Thus similar thing probably happens with Jazz.

You keep also apologizing for casually mentioning some other game, I'm not sure if that's really against the rules here.

But uploading on models resource and such, even if it wasn't illegal it just isn't the cool thing to do since the guys who worked on the project meant to make money from it at some point.

Thus it would be best if the models as such remained under use strictly for the games or perhaps for a direct port to the newer unreal engine, but outside of that? That's wrong.

Just plain wrong.
