PMXImporter for Unreal Engine

PMXImporter is a plugin for Unreal Engine that imports MikuMikuDance PMX models as Skeletal Mesh-centric assets. It provides Pmx Translator with a dedicated PMX import pipeline.

Features

Included :

• Skeletal Mesh and Skeleton import
• Vertex Morph import as Morph Targets (UMorphTarget)
• PhysicsAsset generation (RigidBody and Joint mapping)
• Basic Materials/Textures: Base Color and Metadata
• Reimport support

Out of scope :

• VMD animation import
• Full support for UV/Material/Bone morphs

Requirements

• Unreal Engine 5.6+ (Windows)

Installation

Option A – Copy into your project:

1. Create (or open) your UE 5.6+ C++ project.
2. Place the Plugins/PMXImporter folder into your project's Plugins directory:
   • ProjectRoot\Plugins\PMXImporter
3. Open the project in Unreal Editor. UE will compile the plugin on first load.

Option B - via Fab

• https://www.fab.com/ko/listings/d0d45e1b-c8b1-43a5-b0d4-2ac98b183917

Usage

1. Open your project in Unreal Editor (5.6+).
2. Drag & drop a .pmx file into the Content Browser, or use: Content Browser > Import.
3. PMX import dialog appears. Configurable options:
   • Common: Scale
   • Mesh: Import Morph Targets
   • Physics: Enable Physics, Shape Scale options
   • Material: Create Material Instances
4. Confirm. The pipeline will create SkeletalMesh, Skeleton, Materials, Textures, and PhysicsAsset.

Reimport:

• Right-click the generated SkeletalMesh (or Interchange Source Data) and choose Reimport to reflect changes from the original .pmx.

Morph Targets

• Vertex Morphs are imported as UMorphTarget.

Logging & Diagnostics

• Log category: LogPMXImporter, LogPmxReader

Limitations

Limitations (current):

• No VMD import; limited morph types (vertex only), basic material graph.
• Physics constraints use soft settings; some complex PMX physics setups may require manual tuning.
