If you have an existing Megascans subscription and would like to get unlimited access to Megascans for UE4, just sign in with your Epic Games account. This will link your Quixel Megascans account with your Epic Games account. If you have an Unreal Engine license, you'll see an option to switch to the Unreal Unlimited plan.
If you purchased one of Quixel’s legacy plans in 2019, we’ll also refund you for all your purchases in 2019. This offer will remain available until the end of January 2020.
