FBX SDK - 从角色的 ENodeId 获取 FbxNode

Question

是否可以从枚举 ENodeId 中获取关联的 FbxNode？例如，如果我想从 Character::eLeftHand

获取 FbxNode

我尝试使用 Character::GetCharacterLink(ENodeId, FbxCharacterLink) 然后通过调用 FbxCharacterLink::mNode

从 FbxCharacterLink 中提取 FbxNode

然而这个函数returns对于大多数ENodeIds都是False，所以没有FbxCharacterLink被创建。

character = myScene.GetCharacter(0)
lefthand = character.eLeftHand
lefthand_node = FbxCharacterLink()
character.GetCharacterLink(lefthand, lefthand_node) # False
lefthand_node = lefthand_node.mNode

当我在 Motionbuilder 中使用 Python 和 Pyfbxsdk 编写脚本时，这非常简单，无论骨架对象如何命名，我都可以获得它的 FBXObject

m = character.GetModel(self.BodyNodeObject[o])

和BodyNodeObject是用

生成的

def BodyNodes(self):
    for i in dir(FBBodyNodeId):
        if i[0] == 'k':
            try:
                self.BodyNodeObject[BodyNodesId[i]] = getattr(FBBodyNodeId, i)
            except:
                pass

BodyNodesId只是一个字典

BodyNodesId = OrderedDict({
        'kFBChestNodeId':'Spine1',
        'kFBHeadNodeId':'Head',
        'kFBHipsNodeId':'Hips',
        'kFBLeftAnkleNodeId':'LeftFoot',
        'kFBLeftCollarNodeId':'LeftShoulder',
        'kFBLeftElbowNodeId':'LeftForeArm',
        ...
})

这对我有用

from fbx import *

for i in range(myscene.GetCharacterCount()):
    character = myscene.GetCharacter(i)
    node = character.eHips
    link = FbxCharacterLink()
    while (character.GetCharacterLink(node, link)):
        print node, link.mNode.GetName()
        node = character.ENodeId(int(node+1))
