[fixed] Double Door Shutter is in wrong position

[fixed Dec-2022] This only happens when the standard double door is chosen with the modern frame type B. The shutter between both doors is slightly off the door.

It will be fixed with the next update. Meanwhile you can fix it yourself.

  • Open the BP_StandardDoor blueprint
  • Open the function Add Hardware Offset
  • Search for the green commented area align shutter double door
  • Add the function Get Door Frame Offset and connect it with the multiplier node as seen in the image
  • Compile and Save.

Door seems to flicker or is looking odd

Sometimes the door mesh seems to flicker or the textures look low res. This seems to happen after moving the blueprint around. I am guessing it is a general Unreal 5 issue. You can fix this by ticking either the 'Is Double Door' or 'Flip Door' option twice.

The yellow marker around the door always seems to flicker a bit in Unreal no matter which actor is selected. You can safely ignore this.

How to open the door with a key press

This is for Unreal 5. Unreal 4.x may look a bit different. Use the below settings for the door:
> General
Door Mobility Mobile: The door can open and close
Door Rotation (Location) Set to 0.0 for movable doors.
> Interactive Door
Auto Open Disable

You can either use your Character (Default Pawn Class) or Controller (Player Controller Class).

Open the World Settings and you'll find them under Game Mode. Have a quick look at some tutorials if you're unfamiliar with those two classes.

Open your choice and click on the Class Settings on top of the main editor window. You may have to switch to the full blueprint editor to make those changes. In the Details panel go to the Interface section and add the interface BPI_UI3_Interaction to the list of Inherited Interfaces. Finally add the nodes below and Compile and Save the Character or Controller.

That should be it.
