from above: "you can look through the game’s Blueprint scripts, art assets, and C++ code, and use the assets for your own projects. "
I’ve seen nothing that contradicts how we can use all the assets that Epic has given freely. Use them to your hearts content in personal, hobbiest, or commercial projects. Can’t sell the asset itself, but can use it in commercial projects.
Of course, that’s just my armchair lawyering.
Go crazy!
