EvaluateLocalTransform/EvaluateGlobalTransform return nan values

[Anonymous]

when I am use fbx 2019 sdk to convert fbx to csb,  EvaluateLocalTransform/EvaluateGlobalTransform return 

FbxAMatrix whose elements is nan.  The code is as fallowed.  The error only happen on the 3th/4th keyframe(time=0.233333/0.266667) in the "Bone_Hair_05".

FbxAnimLayer *layer = animStack->GetMember<FbxAnimLayer>(l);
FbxAnimCurveNode *curveNode = layer->GetSrcObject<FbxAnimCurveNode>(n);
FbxProperty prop = curveNode->GetDstProperty(o);
FbxNode *node = static_cast<FbxNode *>(prop.GetFbxObject());
 for (float time = (*itr).second.start; time <= last; time += stepSize) {
                        time = std::min(time, (*itr).second.stop);
                        fbxTime.SetMilliSeconds((FbxLongLong)time);
                        FbxAMatrix *m = node->EvaluateLocalTransform(fbxTime);
}

Then, I try to use "GetNodeLocalRotation/Translation/Scaling" to get data. The first element of FbxQuaternion data is nan. And This is the 3d max file.

It looks like the file is not attached.

Something worth looking for is objects/keys that will produce a scaling of 0, causing a division by 0.

FYI, I did see people using a scale of 0 to hide objects. The FBX does not support this "technique", instead the Visibility flag must be used.

Thank you for your reply. About 0 scale, I try to check it and The problem about 0 scale show the all data is nan.
