RWSkinPLG (0x0116)
The RWSkinPLG section describes the bones of an actor and how these react with the vertices of the model mesh. It is usually found as RWExtension child of a RWAtomic section.
Here is a discrepancy between the format described by gtamodding and the one described by kabbi. The differences are not compatible to each other, but the format by kabbi seems to work, so this is what I will using as well, even though it has some strange properties (see bone matrix).
