I make a animation on Blender importing VRM whit VRM Add-on, all works but importation of .vrm or .vrma from VRM Add-on don't works. Last version of VRM4U, Unreal 5.3.

ImportationError

A issue has openned in GitHub for VRM Add-on https://github.com/saturday06/VRM-Addon-for-Blender/issues/429 but maybe the bug is here

Hi. This may be due to the use of special characters in the folder name. Try placing the vrm files in a standard folder, such as alphanumeric, and importing them. Thanks.

Blenderにインポート / エクスポート する前の VRM はUEに正常にインポートできました。 VRoid Studio で VRM0.0 でエクスポートし、同様の手順を行うと正常にインポートできました。

<使用バージョン> UE5.2 VRM4U_5_2_20240402 VRM Add-on for Blender 2.20.37

報告ありがとうございます。 修正しました。最新のプラグインを利用してみてください。 assimp内で glTFとは異なる3Dモデルフォーマットとして読み込まれていました。優先的にglTFとして読み込みを行うよう変更しています。

Thanks for the report. I fixed the issue. Please try using the latest plugin. It was being loaded as a different 3D model format than glTF in assimp. It has been changed to read as glTF first.
