This Blender addon enables importing and exporting DirectX (.x) files with full animation support.

Key Features:

• ✅ Mesh geometry import/export
• ✅ Material information handling
• ✅ UV coordinates support (multiple UV layers)
• ✅ Normal mapping support (MeshNormals)
• ✅ Vertex color support (MeshVertexColors)
• ✅ Polygon to triangle conversion
• ✅ User-friendly interface panel
• ✅ NEW: Full animation support
• ✅ NEW: Skeletal animation (bones/armatures)
• ✅ NEW: Skin weights and vertex groups
• ✅ NEW: Keyframe animations (rotation, scale, position)

Installation: Standard Blender addon installation via Edit > Preferences > Add-ons

Usage:

• Import via File > Import > DirectX (.x) or using the DirectX panel
• Export via File > Export > DirectX (.x) or panel buttons
• Supports exporting selected objects only
• NEW: Animations automatically imported and exported

Supported Format: DirectX Text (.x) format - ASCII text-based .x files with animation support

Mapping Features

The plugin now supports advanced mapping features:

Normal Mapping

• Imports and exports MeshNormals blocks
• Automatically applies custom normals to imported meshes
• Preserves vertex normal information during export

Vertex Colors

• Supports MeshVertexColors blocks for vertex-based coloring
• Creates vertex color layers in Blender during import
• Exports existing vertex color data from Blender meshes

Multiple UV Layers

• Handles multiple MeshTextureCoords blocks
• Creates separate UV layers for each texture coordinate set
• Exports all UV layers from Blender meshes

Animation Features

The plugin now supports full skeletal animation:

Skeletal Animation

• Imports and exports Frame hierarchy for bone structures
• Creates Blender armatures from DirectX Frame data
• Supports bone parent-child relationships

Skin Weights

• Imports SkinWeights blocks for vertex deformation
• Creates vertex groups in Blender for each bone
• Applies armature modifiers automatically
• Preserves vertex weight information during export

Keyframe Animation

• Supports AnimationSet and Animation blocks
• Imports three animation key types:
  • Type 0: Quaternion rotation keyframes
  • Type 1: Scale keyframes
  • Type 2: Position keyframes
• Creates Blender Actions from DirectX animations
• Exports Blender animations back to DirectX format

Animation Workflow

1. Import: DirectX files with animations create armatures and actions
2. Edit: Use Blender's animation tools to modify keyframes
3. Export: All armatures and actions are automatically included

The README includes test examples:

• test_cube.x (basic mesh)
• test_mapping.x (with mapping features)
• test_animated_cube.x (with full animation support)
