Question

我尝试使用FBX SDK从fbx文件获取动画曲线。我试着在FBX文档中说：http://help.autodesk.com/view/FBX/2017/ENU/?guid=__cpp_ref__import_scene_2_display_animation_8cxx_example_html。这是代码：

        int layersCount = currAnimStack->GetMemberCount(); 

    ///  layersCount = 1

        FbxAnimLayer* layer = currAnimStack->GetMember<FbxAnimLayer>(0);

    //// layer is ok, it's not null

        FbxAnimCurve* curve = inNode->LclTranslation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_X);
        curve = inNode->LclTranslation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_Y, NULL);
        curve = inNode->LclTranslation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_Z, NULL);
        curve = inNode->LclRotation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_X, NULL);
        curve = inNode->LclRotation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_Y, NULL);
        curve = inNode->LclRotation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_Z, NULL);

        curve = inNode->LclTranslation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_X, NULL, false);
        curve = inNode->LclTranslation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_Y, NULL, false);
        curve = inNode->LclTranslation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_Z, NULL, false);
        curve = inNode->LclRotation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_X, NULL, false);
        curve = inNode->LclRotation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_Y, NULL, false);
        curve = inNode->LclRotation.GetCurve(layer, FBXSDK_CURVENODE_COMPONENT_Z, NULL, false);

但无论我如何尝试，曲线始终为空。同时，在3ds Max曲线中显示。那可能是什么错？

从3ds Max导出期间的操作为我提供了我需要的曲线：

转到Motion-＆gt; Trajectories并按折叠。

无法从FBX获得曲线
