                    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:

                    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)
```

使用BetterExport的版本：
```python
import bpy
import os
import math
from io_import_scene_unreal_psa_psk_280 import *
from better_fbx 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
                        
		    bpy.ops.object.select_all(action='SELECT')
			bpy.ops.better_export.fbx(filepath=fbx_file,my_fbx_format="binary",use_selection=True,use_visible=True,use_only_root_empty_node=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

from io_import_scene_unreal_psa_psk_280 import *

psaDirPath = 'C:\\Users\\BlueRose\\Desktop\\BLUEPROTOCOL\\Game\\Animations\\Enemy\\E000'

# 清空场景并且导入模型

            print(fbx_file)
            
            psaimport(psa_file)

			bpy.ops.scene.new(type='EMPTY')
			bpy.ops.object.select_all(action='SELECT')
			bpy.ops.object.delete()
```

**绯红结系批量转换代码**：
```python
import bpy
import os
import math
from io_import_scene_unreal_psa_psk_280 import *
from better_fbx import * 

for action in bpy.data.actions:
    bpy.data.actions.remove(action)

# 导入骨骼以及动画(所有NLA)

    # print(currentSkeleton.animation_data.action)
    # print(bpy.data.objects["SM_ch0100.ao"].animation_data.action)

```


## 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
```

## NLA Action遍历
```c++
import bpy
import os
import math

for action in bpy.data.actions:
	print(action)
	action.name
	
	bpy.data.actions["AS_ch0100_016_AL_walk"].name = "AS_ch0100_016_AL_walk"


bpy.context.object.animation_data.nla_tracks.active = bpy.context.object.animation_data.nla_tracks[0]


# You can set an object's action like:
# object.animation_data.action = action
print(bpy.data.objects["SM_ch0100.ao"].animation_data.action)
```

```

取得当前激活状态的NLA Action
```python
for i in bpy.data.objects:
    for j in i.animation_data.nla_tracks.values():
        for k in j.strips.values():
            if k.active:
                print(k)
```

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。
**导出的时候还需要注意：1、FPS是不是设置成30，默认是24。2、导出选项需要去掉添加叶子骨骼节点的选项**

# 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。
