Hello, I love your plugin, So easy to import Vroid model.
but, When I build package project its error and appear log like this

I don't know how to fix it. Thanks...

My Step:

1. Import File_A.vrm and File_B.vrm to UE4.
2. integrate ALSV with File_A_ue4mannequin (Skeletal Mesh) by following your video step by step.
3. Select File_B_ue4mannequin (Skeletal Mesh), Assign skeletal to File_A_ue4mannequin (Skeletal Mesh).
4. In Anim_BP, Editor mode, Change Vrm Meta Object of VrmSpringBone from File_A_VrmMeta (VrmMeta) to File_B_VrmMeta (VrmMeta).
5. UE4 Crash

Assertion failed: Pose.IsValidIndex(BoneIndex) [File:E:\Program Files\EpicGames\UE_4.24\Engine\Source\Runtime\Engine\Public\BonePose.h] [Line: 546]

Things I tryed:

1. Change skeletal mesh and VrmMeta in runtime.
2. Disable VrmSpringBone node first and change skeletal mesh and VrmMeta, once VrmSpringBone node active, game crash.
3. Check and assign new bone index to File_B_VrmMeta

Still crash when add other VrmMeta data to VrmSpringBone Node.

if you have any idea please help, thanks

Hello again, i have a issue to use in UE5, i change the Developer mode to UncookedOnly, but the issues continue.

こんにちは、UE4.25とUE4.24でWindows64-bitパッケージしてみたところ、パッケージは成功するもののgameが起動できない現象がおきましたのでご報告いたします。
なお、UE4.23とUE4.22では問題なくパッケージできるようです。

サードパーソンにVRM4Uを入れてパッケージする。

VRM4U-20200611

UE4.25でゲーム起動時のエラー

UE4.24はメッセージは特にでないでそのままゲームが起動しないという状況でした。

Hello, sorry for bothering you but I'm currently having an issue with your plugin. The problem is that I'm unable to build my game due to the VRM4U plugin. This is the error I get when I try to package my game:

VRM4UImporter.Build.cs can be found in "VRM4U\Source\VRM4UImporter" (The 'UnrealEd' reference can be found in line 19)
Additional information:

URE Version: 4.25 (latest, C++ project, Visual studio 2019 is installed)
Packaging for Windows (64-bit)
Yes I am using the UnrealEngine_VRM4UPlugin repository version of VRM4U (Latest version, working fine in the editor, it's located within the Plugins folder of my project)
I have also included a log file
ProjectMare.log

when i import a vrm model everything works but the model dose not render i think

こんばんは、UE４．２４で1. パッケージ化してランタイムロードしたとき、MorphTargetが動作しない下記メッセージがでましたので情報共有いたします。
UE4.24のデバック画面の表情変更動作は問題ありませんでした。

またUE4.25はパッケージランタイムロードで下記のメッセージはでていないので

when im trying to launch or package the project I encountered error message please see below thanks !

LogPlayLevel: Error: ERROR: Missing precompiled manifest for 'Launch'. This module was most likely not flagged for being included in a precompiled build - set 'PrecompileForTargets = PrecompileTargetsType.Any;' in Launch.build.cs to override.

Sorry, I don't know where to ask this question so I ask here. I see your video here (https://youtu.be/ohuoVnCEX5k) and I see that my character's hair in my project acts like the one on the left in game but acts like the right in Physics Asset editor. I imported with "No Physics Asset" unchecked so I don't know why it works like that. I want the hair physics to work like the right one. Sorry I am quite new to UE4 and cannot read japanese.

hello ruyo,
I'm using ue4.22.3.
its all good in the editor but if I launch the game or package the game ,
textures will disappear.
I don't know how to solve it. Please help.

here's the video: https://www.youtube.com/watch?v=9-DdeCwzv-I
(I only record the launching part but it will be the same result if I package it.)

Hello Ruyo,

Do you have any solution for this? Thanks in advance!

I'm currently having issue that the plugin is not visible at plugins menu in UE 4.26. I've tried both pakaged one from here and one linked with Epic Games.

Everytime I package the game using VRM plugin always error.

I tried to create new project and then package without VRM plugin I have no issue, but when I package with VRM package will error.

1. I downloaded the plugin in here https://github.com/ruyo/VRM4U/releases/tag/20200625

I choose VRM4U_4_20_20200625.zip , downloaded , extract, then I copy folder "plugins" to my game folder project

2. I Click and drag VRM file inside editor and put it on map

3. Package the game

Here I provide Video for error to make it clear
https://youtu.be/XXI6Pjddoqk

Also the log
MyProject.log

Really appreciate if you can provide video tutorial how to fix it. I really need help @ruyo

Hello, I wanted to try out the plugin in UE4. when packaging project I receive this error: Could not find definition for module 'VRM4U'. I tried adding the source folder to the plugin but now I am getting this

Is there anyway I can fix this? I am fairly new to Visual Studio and C++ and my project is fully Blueprint based

I just recently downloaded UE4.25.3 and followed a Youtube Video - https://www.youtube.com/watch?v=EwCxPRIDyCk

I don't think the plugin is showing at all? Am I doing something wrong?

Hi,
I love your plugin and would love to use my Vroid characters with the new Niagara improvements. Would it be possible to compile for 4.25? Cheers.

I'm trying to package from unreal, but get the error:

"ERROR: Could not find definition for module 'VRM4U', (referenced via Eureka_II.uproject -> VRM4U.uplugin)
PackagingResults: Error: Could not find definition for module 'VRM4U', (referenced via Eureka_II.uproject -> VRM4U.uplugin)#"

If I move the files from https://github.com/ruyo/UnrealEngine_VRM4UPlugin manually I get this text:

"The following modules are missing or built with a different engine version.
VRM4U
VRM4ULoader
VRM4UImporter
VRM4UMisc"

... And if I press yes to rebuilding them I get this message...

"Could not be compiled. Try rebuilding from source manually"

It would make me so happy to be able to package, but I don't understand how to use VRM4U plugin with source code.

...

UPDATE

It works with version 4.23.1, but not 4,24.1

Tried packaging in android = fails
win64 = fails but I think its because I havent installed visual studio 2019 and C++, does it affects android packaging?

Steps I take:

1. put VRM4U release 20200725 to UE4 plugins
2. make games, build it, play it no problem (except android launch)
3. Put source folder from https://github.com/ruyo/UnrealEngine_VRM4UPlugin to UE4 plugins/VRM4U
4. still cannot package

Please help ya thanks!

Hello. I wanted to try out VRM4U in an Unreal Project.

I'm using Unreal Engine v4.24.3 and the latest VRM4U Unreal Extension(the one from the private repo).
I managed to add it, but when I compile with it, things go wrong. I tried it even in an fresh project, but it gives me this error:

LogPlayLevel: Error: ERROR: Could not find definition for module 'VRM4U', (referenced via CodenameSakura.uproject -> VRM4U.uplugin)

The plugin is added in the project plugins folder. I have Visual Studio 2017 Community installed and configured(there is also VS2019 Professional).

This is my log:
CodenameSakura.log

Could you please help me or tell me what I'm doing wrong?
Thank you.

Hey Ruyo, first of all thank you soo much for creating the plugin. It means a lot for me and my team.
I've notice that you import the physic as well but mine goes a little bit wild. Is it the tick?

How to import animations in fbx to UAnimSequence with VRM4U?

When I load a VRM on UE4 using your plugin, I notice the vertex count is abnormally high.
This was confirmed again on Blender after I exported it from UE4 as an fbx file and load it on Blender, which prevents me from posing it due to extremely low FPS caused by high vertex count.

When I pick one vertex on the hair on Blender, it says it is actually 132 vertices as below:

Is this a bug? Or Am I missing something?

hi Ruyo it's very cool work. But,

include VRM4U plugin in UE4, than package will get this error:

Hello, I would like to use your plugin but actually I can't because the link : https://github.com/ruyo/UnrealEngine_VRM4UPlugin doesn't work...

Is it possible to update it ? Thanks. :)

I've been trying for hours to get this to work on my Mac. Is this plugin compatible with Macs or is it Windows only? I haven't seen any information saying either way.

I can't tell for sure, but it seems as if when I unzip the file, it does not create the proper folder hierarchy when unzipping on a mac. I've tried using the default unzip options, the mac version of Winzip, and even unzipping from the terminal, and it still will not unzip properly.

I used ue4.25.0.
Everything is fine in the game, but if I launch the game pack,The skeleton mesh seems to be

2：Screenshot of import at Game：

I tried to replace the offical mannequin model directly with the imported version of ue4mannequin(by vrm4u). Every bone was aligned, but there was a severe rotation distortion.
By comparing the skeletal structure of the two models, I found that their skeletal space is different.
The X-axis of each bone in mannequin is parallel to the direction of the bone, whereas the X-axis of each bone in the VRM4U model appears to be oriented to the left hand side of the model.
If this difference can be corrected , the imported model might be used directly as mannequin without retarget at all. Is it possible to fix it?
ps. Your works is definitely great!

Hope the author can answer, thanks in advance

Hello ruyo. I'm very interested in this plugin, but I can't import some models due to the DeadlyImportError exception (both in the release you provided and in my compilation of the plugin with your assimp).
This exception is only thrown for some vrm models like this. I tested some different models, and the plugin works fine. The mentioned model causes problems in more than this plugin (I've also tried another plugin that can convert the VRM format, but the final results were weird), but can indeed be loaded using the VRMViewer.
The exception was from LazyDict::Retrieve(unsigned int i) in glTF2Asset.inl (line 260):

 // read it from the JSON object
    if (!mDict) {
        throw DeadlyImportError("GLTF: Missing section \"" + std::string(mDictId) + "\"");
    }

where mDictId was meshes, i was 1,
mObjs was

mObjsByOIndex was

The callstack was:
glTF2Asset.inl:

glTF2::LazyDict<glTF2::Mesh>::Retriete line 260
glTF2::GLTF2VRMMetadata::Read line 1554
glTF2::Asset::Load line 1814

LoaderBPFunctionLibrary.cpp:

VRM4UImporterFactory.cpp:

...(Engine functions)

Could you please try that model using the plugin? It would be perfect if this problem gets solved.
Anyway, thanks for sharing such a wonderful plugin. ありがとうございます！

Hey, i've been trying to do this VRM4U stuff for awhile and i'm having some hard time importing my models in, Is there any tips i may get?

I'm Running UE4 Version 4.25,

I've Created my character

I've (freshly) installed - UE4 v4.25

I've (freshly) installed the latest VRM4U Plugin for v2.25

I've tried dragging my character from my Desktop to UE4 and nothing..it shows an error symbol where my mouse cursor should be.

So i manually put it in my Project-File's Content folder, and it ask me if i want to "import assets",
i click "Yes".

Then i checked the logs and it says.."could not import" Error.

I've been at this for awhile now and i don't know what else to do.

I downloaded the plugin and put it in the "Plugins" folder of Unreal Engine 4.21-release github. But every time I get this error. How can I fix it?
