In-game editor

I have a problem loading the in-game editor that I downloaded from epic. Any help

You're going to have to provide a lot more information, no one on the planet can help you based on such a vague description. Is the tool not able to purchase, is it not downloading, does it not show in-game, do changes not apply, etc... You see how many different stages this could go wrong, and why you have to be more precise?

Epic version does not support In-Game Editor. That's official.

Sad to hear that. But thanks
