I am having problem with calculating bind pose for some bones of a given skeleton using FBX SDK.
I can easily get bind pose matrices for the bones affecting a mesh from the FbxClusters.
I can also calculate bind pose matrices of bones which have no FbxClusters assigned to them if these bones have parent bones which have clusters assigned to them by the method described in the last post here: http://forums.autodesk.com/t5/FBX-SDK/Skeleton-Bind-Pose-for-bones-not-linked-to-clusters/m-p/417362...
Now the problem I am having is how to calculate bind pose matrices for the bones which have no FbxClusters assigned to them and which have either no parent nodes or their parent nodes have no FbxClusters assigned to themselves as well. (Please note that FbxPose has no matrices for these bones either)
In the image below I have outlined examples of such bones in red:
Any help would be highly appreciated.
