Hello , I’ve finished the tutorial from: > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline. These resources now live on a new community-run Unreal Engine Community Wiki — ue4community.wiki! You will be able to find content from the official... result: [https://i.imgur.com/KsHGt8w.webm](https://i.imgur.com/KsHGt8w.webm) everything works ok, but, when I try to open the BatteryHUD BluePrint
