Universal Doors (V.2) Unreal 5 :: Documentation

Version 2 of the Universal Door Blueprint is an improved version for Unreal 5 supporting Nanite and Lumen.

Note that the Unreal 4 version does not have this update and is optimized for performance (draw calls) instead. It is slightly different and does not have double doors or the barn door type. It will not be updated.

Door Parts

An overview of all the door parts that can be changed. The door opens to the inside. Handle Outside means the door handle on the other side of where the door opens to. Which is usually the entry door handle.

Something in general: There are many settings available. Let me know if you think something should be available that isn't at the moment.

Quick Guide

There are 4 blueprints available:
  • BP_StandardDoor
  • BP_SlidingDoor
  • BP_BarnDoor
  • BP_CustomDoor

They have the same settings more or less, with the exception of the Custom Door blueprint which is made for using any door or frame mesh (gates, etc). See further down for more info.

The main door types (standard, sliding, barn) have a double door option, share hardware and door meshes, and have a feature to auto align doors to the frame. All doors can open and close when the player approaches, or with a key press.

General - Door - Frame

> General
Frame Type Select a frame style from the list
Door Size Select a size from the list. The letter in brackets indicates what door size is initially used. For example (M) means it is one of the medium sized doors that are located in the Content/Doors/M folder.
Door Type Select a door style from the list. There are 5 pre-set styles available. You can also choose a Custom Door. See in the Door section for detals.
Door Mobility
  • Static: A door that doesn't move. Can use lightmaps
  • Stationary: Use Static instead
  • Mobile: The door can open and close
Flip Door This will flip the door so the handle is on the opposite side.
Is Double Door Will turn this into a double door.
Door Rotation (Location) How far a non-movable door will stand open. Set to 0.0 for movable doors.
Door 2 Rotation (Location) How far the 2nd non-movable door will stand open. Set to 0.0 for movable doors.

> Door
> Materials Door Add an array element for each of the material you want to change.
Index [0] The array ID equals the material ID (in Unreal). If you would want to change index [2] you would need to add 3 array elements and leave [0] and [1] empty.
Glass Material Door Add a material for the Glass Mesh which is seperate for door styles 4 and 5.
Custom Door Mesh You can add a custom door mesh here. Set the Door Type to Custom Door. Then check the letter in brackets, like (M). Go to the Doors/M folder and choose one of the additional doors in there.
Custom Door Glass Mesh Add an optional custom glass mesh for your door.
Note: Want to use your own door? Set the door type to <i>Custom</i> under General. Then add your door as <i>Custom Door Mesh</i>. Rotate the door with <i>Door Rotation Correction</i> if necessary. Hit <i>Calculate Scale and Offset</i> to auto-fit the door into the choosen frame.
> Advanced  
None S-M-L Door Tick this to enable auto scale for doors that don't fit into the frame as they are. This tells the blueprint that the door doesn't have the standard size and position for this frame.
Door Rotation Correction Use this to rotate the custom door mesh into the correct direction.
Thickness Scale You can add a thickness scale here. So you don't have to repeatedly change the value in the <i>Custom Door Scale</i>
Calculate Scale and Offset Click here to auto-fit the door. This works best when the door doesn't have any handles or shutters or other elements that stick out of the door box shape.
Use this if you want to use one of the doors from the package where the size isn't available. Scaling may be visible.
> Custome Door Offset Modify the calculated offset if necessary.
> Custoom Door Scale Modify the calculated scale if necessary.

image
> Frame
Has Top Window The door can have a top frame part with a fixed window. Only frame style 'standard' available for that window.
Top Window Scale Z Adjust the height of the top frame window
> Materials Frame Add an array element for each of the material you want to change.
Index [0] The array ID equals the material ID (in Unreal). If you would want to change index [2] you would need to add 3 array elements and leave [0] and [1] empty.
> Materials Top Mesh Add custom materials here for the top window mesh. If empty the frame materials will be applied.
Glass Material Top Change the glass material here if needed.
Custom Frame Mesh Add a custom frame mesh here. The bounds need to be the same as the standard frame meshes. (See custom door mesh)
Custom Top Mesh Add a custom frame top mesh here.
Custom Top Glass Mesh Add an optional custom glass mesh for your top frame window.
> Advanced  
Frame Thickness Scale This will scale the frame, the door, and all attached hardware. Use with care.
Door Frame Offset tbd
Top Window Offset Add a height offset here (eg to make space for a beam)

Handle Height Change the height where the handles are placed from the floor here.
Lock Height This changes the height of the additional lock mesh relative to the handle. Negative values will be below the handle and positive values above it.
> Advanced  
Handle Offset This is the offset from the handle to the door. Some handles don't have plates and you need to use this to move the handle closer to the door.
Handle Offset Outside Additional offset for the outside handle.
Handle Horizontal Offset The distance from the door edge is usually standard and depends on the hardware used. You may change this here for visual reasons.
Entry Handle Vertical Offset Change the position of the entry handle.
Door 2 has Lock Plates Weather the 2nd door of a double door has lock plates
Move Handle Outside This enables the movement of the handle set as the entry handle.

Interactive Door

> Interactive Door
Auto Open This is the default for interactive doors. The door will open when a player is entering the collision box. The door mobility needs to be set to 'Mobile' in the General Settings.
Note: You need to send a message to the door if Auto Open is disabled. You can use the 'Blueprint Interface' to do that. It is implemented in the provided character in the Blueprint/Others folder. It is relative easy to implement.
Initially Open This will open the door as soon as the walk through starts. You will hear it opening.
Desired Rotation (Location) How far should the door open?
> Collision Location Offset Change the location of the wireframe collision box.
> Collision Scale Change the size (scale) of the wireframe collision box.
> Advanced  
Text Offset In / Out Adjust the position of the pop up text for non automatic doors.
Text Hint Change the pop up text here.
Text Render Color Change the color of the pop up text here.
Closing Sound Add a sound asset here or leave the default sound
Opening Sound Add a sound asset here or leave the default sound
Note: Standard double doors will only have one door opening. Use the Flip Door switch in the general settings to change which door opens.
Sliding doors have an additional option to open both door.

Hardware

> Hardware
Add Hinges Weather to add hinges to the door.
Hinges Door Mesh
Hinges Frame Mesh
Change the hinges meshes here if needed. You can add your own hinge mesh but it needs to be positioned the same way as the standard ones.
> Materials Hardware An a material array element for each ID
Index [0] Index [0] should be the metal part of any of the hardware meshes.
Hinges Amount How many hinges should the door have? 2 or 3 is standard.
Add Shutter Weather to add shutter meshes to the door and frame.
> Advanced  
Edge Distance The distance from the top and bottom edge to the hinges
Shutter Door Mesh The mesh for the shutter in the door
Shutter Frame Mesh The mesh for the shutter attached to the frame

Custom Door Blueprint

Update Dec-22 2022.

This blueprint lets you combine any door and frame mesh to an interactive (opening) door or gate.

Quick guide

  • Add the main door mesh
  • Correct the rotation
  • Add the frame mesh
  • Correct the frame rotation
  • Scale and position the frame
  • Use Door Offset Frame and Custom Door Scale to align the door to the pivot of the hinges
  • Use the Hinge and Handle Offset to fine tune the position
  • Add the remaining door meshes if there are any
  • Add hardware and handles if needed

image
> General - same as standard blueprints
> Door
> Door Meshes Add an array element for each mesh that combines as the door.
Index [0] The array ID equals the material ID (in Unreal). If you would want to change index [2] you would need to add 3 array elements and leave [0] and [1] empty.
Static Mesh Add a static mesh
Materials Add material override(s) for this mesh.
Door Rotation Correction Align the door to the standard door or frame
> Door Offset Frame The general offset of the door relative to the frame. Align the red dot to the point the hinges pivot point would be. The door will rotate around that pivot.
> Door Offset Hinge This will offset the door to the red dot (pivot) if necessary.
> Door Offset Handle This aligns the little white dot. Align it to the end of the door where the door shutter would be. (Not where the handle would be)
> Custoom Door Scale Modify the scale if necessary.
> Advanced  
Calculated Door Offset This is an info only. You can't change this. Change Door Frame Offset instead
Custom Door Size Info only.
Scaled Door Size Info only.

image
> Frame
Custom Frame Mesh Add the frame mesh
Note: Any additional parts of the frames would need to be added manually. You can use CTR+G (or right click menu) to group the blueprint with those meshes.
> Materials Frame Add an array element for each of the material you want to change.
Frame Rotation Correction Use this to give the frame the same direction as the stand-in frame.
Frame Scale Scales the frame

image
> Handles
... ...
> Materials Handles Add materials here to replace the existing materials for all handles and plates.
Door Thickness Offset This offsets the handles and plates on the inside if the door is not 4cm (units) thick.
Handle Height Change the height where the handles are placed from the floor here.
Lock Height This changes the height of the additional lock mesh relative to the handle. Negative values will be below the handle and positive values above it.
> Advanced  
Move Handle Outside This enables the movement of the handle set as the entry handle.
Handle Horizontal Offset The distance from the door edge is usually standard and depends on the hardware used. You may change this here for visual reasons.
Handle Offset This is the offset from the handle to the door. Some handles don't have plates and you need to use this to move the handle closer to the door.
Handle Offset Outside Additional offset for the outside handle.
Handle Vertical Offset Outside Change the position of the entry handle.
