Content:

Access None Errors in New Project

Can't Move Using VR Controller

[Fixed] Only One Variation Name In List

Info Section for Variation doesn't update

[Legacy] Asset materials change when hitting [F]

Floorplan appears to be unscaled

TV not playing

Failed to load [...] P_Tablet12

Some images on the VR tablet are too dark or too bright.

[Fixed] [5.3] GameMode Blueprint Error

Menu is Empty

Access None Errors in New Project

Symptom
There are a lot of Access None trying to ... in the message log after play testing a project.

Cause
The interface tries to calculate the cost, but no prizes are set in any of the Variation actors.

Solution

  • Open the blueprint library BFL_Edit
  • Open the function Make Details Price and Text
  • Add a Is Valid node as seen in the image to check the Variation Actor isn't empty (none)
  • Compile and Save the function library

Can't Move Using VR Controller

Problem

Player cannot move with VR controller

Cause

There is an error in the Input Mapping Configuration file

Solution

Move is set to the X-Axis. It should be the set to 2D- Axis instead for both VIVE and OCULUS controllers.

Please change this in UI / Etc / Input / MC_ArchViz_UI3 and save the changes.

Fixed

2024-9C (October 2024 update)

[Fixed] Only One Variation Name In List

Problem

There is only one variation in the list named Variation 0 when selecting some of the objects in the scene.

It is caused by a logical error when the amount of variations for the list is calculated. It happens if there are only materials set and not their names.

Work Around

Add actual names to the names array in the Variation actor.

Fixed

In Update

image

Info Section for Variation doesn't update

Problem

The info section in the Edit Mode widget doesn't update when selecting another variation from the list. Although there is an object info array element added for this variation.

Temporary Solution

  • Open the Main Menu Widget
  • Find the function Set Variation By ID
  • Connect the Completed pin to the branch pin as seen in the image.
  • Compile and Save the widget
  • image

    [Legacy] Asset materials change when hitting [F]

    There might be a case where the UI gets stuck in Edit Mode. Meshes get changed by hiding or un-hiding the menu by pressing [F] or clicking (B) on the gamepad. To fix this yourself
    • Open the UI3_MainMenu widget
    • Open the Function Hide All Sub Menus
    • Change the nodes to look as shown in the image
    • Compile and save the widget

    This will be fixed in an update soon.

    image

    Floorplan appears to be unscaled

    Since either 5.1 or later the floorplan occasionally seems to un-scale itself. You can easily fix this by
    • click on the box Update Blueprint in the Info Map
    • or make any change to the Info Map's settings
    • moving the info map and then undo the move
    This may happen again next time you open the editor.

    I've been trying to find the cause for this. But despite many hours and some different approaches it just doesn't go away.

    I'll keep trying and update the project as soon as this issue is solved or maybe it solves itself one day without an apparent reason. The same way it got introduced.

    image

    TV not playing

    Somehow the BP_TVPlaying actor is set to a movie that doesn't exist in the folder.

    Please open this blueprint in the blueprint editor

    • Click on the variable Media Source
    • Change it to CliffHouse_Low
    • Save and Compile

    Finally check if the actor in the level has the same media source set. And look into your directory if the actual movie (MP4 file) is there. Sometimes only the unreal actor is there but not the movie.

    Failed to load [...] P_Tablet12

    Failed to load /Game/ArchVizUI_V3/UI/Etc/SM/P_Tablet12.P_Tablet12 Referenced by P_Tablet12_GEN_VARIABLE

    A couple of users messaged me that they get this error message. The tablet seems to miss its texture, or the texture isn't accessible. Make sure you use the SDot VR game mode for VR. I'm not sure what happened there. Please check the following:

    • open the Blueprint SDotUI3_CharacterV3
    • look for the tablet mesh in the character viewport
    • see if it has its material applied

    image
    The tablet lives in the folder Content/ArchVizUI3/UI/Etc/SM

    The material is in the folder Content/ArchVizUI3/UI/Mat and is called M_MobileDevices01_i01.

    Please reassign the material, if the material isn't applied in the static mesh browser for the tablet or in the character.

    image

    Some images on the VR tablet are too dark or too bright.

    Too Bright

    This is a side effect of using the dynamic sky blueprint. You need to turn down the brightness of all text and image elements. Follow the link at the end of this section.

    UI Design
    UI Color Set Used Set it to Index [3]
    UI Advanced Design
    VR Preview Brightness Set it very low, like 0.05

    Too Dark

    There was a bug where lowering the brightness is applied twice for some image. Change the widget UI3_Image to look like the image. This has been fixed in an update.

    Using Game Modes

    image

    [Fixed] [5.3] GameMode Blueprint Error

    You might get an error when you hit the play button in the editor.

    The Game Modes blueprints contain a node to enable or disable the VR headset. The node Enable HMD is not available in Unreal Engine 5.3 unless the OpenXR plugin is enabled. All other engines don't have that problem as far as I know.

    To solve this you can

    • Enable the OpenXR plugin.
    • Or open the 4 game mode blueprints in the ArchVizUI3 / UI / Blueprints folder, switch to full blueprint editing mode, and remove the node Enable HMD. Compile and save the blueprints.

    Menu is Empty

    New Info Map

    The UI may have no menus if you place a brand new info map into your level. The UI is defined in the Main Menu Layout array. You can copy the info map from the demo scene into your scene.

    Updated Scene

    There might be no sub panels after you updated the UI3 project to a newer UI version. This is because the way the UI is stored in the Main Menu Layout array has changed. Read how to update the UI Design at the link below.
