UModel逆向拆解流程

UModel逆向拆解流程

00 步骤

• 软件准备
  • UModel: UE Viewer | Gildor’s Homepage
  • Blender: blender.org - Home of the Blender project - Free and Open 3D Creation Software
  • Blender psk导入插件: Unreal PSK/PSA (.psk/.psa) — Blender Extensions

• 找到游戏Paks所在的目录类似...\Project\Content\Paks

• 使用UModel进行预览并导出psk文件

  • 如果能确认UE版本最好, 无法确认的情况下只能尝试
  • 如果对方使用了比较新的UE版本, 则可能需要使用对应的UE中的SDK重新构建UModel
    • UModel源码工程中libs/oodle中的ReadMe读一下, 会直到从哪里获得oodle的SDK
  • SMTVV对应的版本是4.26/4.27, 且需要关闭动画导出, 可以导出蒙皮文件.

• 进入Blender, 按照以下步骤安装psk导入插件

  For Blender 4.2 and higher, it is recommended to download the latest version from the Blender Extensions platform.

  For Blender 4.1 and lower, you can install the addon manually by following these steps:

  1. Download the .zip file of the latest compatible version for your Blender version (see Legacy Compatibility).
  2. Open Blender.
  3. Navigate to the Blender Preferences (Edit > Preferences).
  4. Select the Add-ons tab.
  5. Click the Install... button.
  6. Select the .zip file that you downloaded earlier and click Install Add-on.
  7. Enable the newly added Import-Export: PSK/PSA Importer/Exporter addon.

• 导入psk文件后, 将父物体的缩放调整为0.01, 然后应用变换

• 此时可以导入Unity并正常使用
