Hi,
In the FBX SDK, the name property on the FbxNodeAttribute objects (FbxMesh, FbxCamera, FbxLight, etc.) is not mandatory and, therefore, it is up to the application that create the FBX scene to decide if it wants to put a name on them or not! Typically, the name is specified in the FbxNode object that "owns" the FbxNodeAttribute (rarely on the FbxNodeAttribute itself). However, since the name is not really enforced anywhere in the FBX, someone may still decide to not fill this property of the FbxNode. This is not very practical and can definitely cause some issue , but it is still doable 😉
In your code snippet, you should probably do something like this:
FbxNode* child = node->GetChild(i);
FbxMesh* mesh = child->GetMesh();
const char* n = child->GetName();
const char* mn = nullptr;
if (mesh) mn = mesh->GetName();
if (strlen(mn) > 0) { // there is a true name on the FbxMesh object
...
}
...
If the node correctly have a name (in 99.9% of the cases it will), then you will be able to get it with 'n' despite the fact that 'mn' remains empty!
In your exact case, I don't know where the FBX data is coming from but if you cannot get a name even with child->GetName() then you definitely have a scene that did not name its objects!
