Hi Robert,
Lastest change (update to FBX 2012.1) introduced a regression. It didn't take
materials' order into consideration. The line
lMaterialLayer->GetDirectArray().SetAt(it->second.getIndex(), lMaterial);
has been replaced by
_curFbxNode->AddMaterial(lMaterial);
because KFbxLayerElementMaterial::GetDirectArray() is now private and we can't
access to it.
However, pushing back the material at the end of the vector is wrong.
We can use the (now) public attribute KFbxLayerElementMaterial::mDirectArray,
as in this submission.
>From trunk rev 12447.
