# 清空数据

                    bpy.ops.object.delete()
                    pskimport(psk_file, bReorientBones = False)
                    # 使用SmoothShading
                    for obj in bpy.data.objects:
                        if obj.type=='MESH':
                            obj.data.use_auto_smooth = True  
                            obj.data.auto_smooth_angle = math.radians(180)
                            currentmesh = obj.data
                            for setting in currentmesh.polygons:
                                setting.use_smooth = True
                                
                    # 输出骨骼模型
                    bpy.ops.object.select_all(action='SELECT')
                    bpy.ops.export_scene.fbx(filepath=fbx_file,add_leaf_bones=False)
```

直接生成fbx版本
```python
import bpy
import os
import math
from io_import_scene_unreal_psa_psk_280 import *

pskPath = 'C:\\Users\\BlueRose\\Desktop\\ScarletNexus\\Game\\Character\\wp\\wp0100\\04_Mesh'

for modelroot, modeldirs, modelfiles in os.walk(pskPath):
    for f in modelfiles:
        if f.endswith('.psk'):
            psk_file = os.path.join(modelroot, f)
            fbx_file = os.path.splitext(psk_file)[0] + ".fbx"
            # 清空场景
            bpy.ops.object.select_all(action='SELECT')
            bpy.ops.object.delete()
            pskimport(psk_file, bReorientBones = False)
            # 使用SmoothShading
            for obj in bpy.data.objects:
                if obj.type=='MESH':
                    obj.data.use_auto_smooth = True  
                    obj.data.auto_smooth_angle = math.radians(180)
                    currentmesh = obj.data
                    for setting in currentmesh.polygons:
                        setting.use_smooth = True
                        
            # 输出骨骼模型
            bpy.ops.object.select_all(action='SELECT')
            bpy.ops.export_scene.fbx(filepath=fbx_file,add_leaf_bones=False)
```
# PSA
注意：该脚本因为Blender运行bug，会导致输出的FBX文件越来越大，越来越慢。一次转换的量不建议超过50个。建议分几个文件夹，同时开多个Blender一起转换。
```python
import bpy
import os
import math
from io_import_scene_unreal_psa_psk_280 import *
pskPath = 'C:\\Users\\BlueRose\\Desktop\\BLUEPROTOCOL\\Game\\Character\\Enemy\\E000_00\\Model\\SK_CH_E000_00.psk'
psaDirPath = 'C:\\Users\\BlueRose\\Desktop\\BLUEPROTOCOL\\Game\\Animations\\Enemy\\E000'

# 清空场景并且导入模型
for root, subdirs, files in os.walk(psaDirPath):
    for f in files:
        if f.endswith('.psa'):
	        bpy.ops.scene.new(type='EMPTY')
            bpy.ops.object.select_all(action='SELECT')
            bpy.ops.object.delete()
            pskimport(pskPath, bReorientBones = False, bImportmesh = False, bImportbone = True)

            psa_file = os.path.join(root, f)
            pskDirPath = os.path.dirname(pskPath)
            fbx_file = os.path.join(pskDirPath,f) 
            fbx_file = os.path.splitext(fbx_file)[0] + ".fbx"
            print(fbx_file)
            
            psaimport(psa_file)
            
            bpy.ops.object.select_all(action='SELECT')
            bpy.ops.export_scene.fbx(filepath=fbx_file,add_leaf_bones=False)
			
			bpy.ops.scene.new(type='EMPTY')
			bpy.ops.object.select_all(action='SELECT')
			bpy.ops.object.delete()
```

## 添加平滑组
```python
import bpy
import os
import math

for obj in bpy.data.objects:
    if obj.type=='MESH':
        obj.data.use_auto_smooth = True  
        obj.data.auto_smooth_angle = math.radians(180)
        currentmesh = obj.data
        for setting in currentmesh.polygons:
            setting.use_smooth = True
```

导出动画方法：
1. 选择骨骼模型，右键点击Open(add to locate set)，之后按o。
2. 选择动画资产（AS开头），右键点击Open(add to locate set)。
3. 点击Tools - ExportCurrentObject，就可以导出指定的动画。
4. 如果选择多个动画的情况下，在Blender psk/psa插件中可以勾选`All actions to NLA track`
5. 导出动画时，在烘焙动画选项中选择全部动作、NLA片段。所有动画数据都会以NLA Clip的方式存储。
6. 导入UE就可以显示所有的动画数据。

# UModel
## CMD启动
```bash
D:\OtherTools\GameAssets\umodel_win32\umodel_scarlet_nexus_v5.exe -path=C:\Game\ScarletNexus -out=C:\Users\BlueRose\Desktop\ScarletNexus -game=ue4.26 -aes=0x48AE8311350417BDC50A440FCD0E98B2FA6BCEAE3EDA8D0E24881F205E6C4540
```

## 取得资产路径
1. 批量选择动画资产
2. 右键点击Copy package path

# 解决Blender导出问题的根骨骼问题
使用Blender的**Better Fbx Importer & Exporter** addon就可以解决问题。
