ModelPart.partToWorldMatrix

Gets a matrix which transforms a point from this part's position to a world location
Recommended to use this in POST_RENDER, as by then the matrix is updated
In RENDER it will be 1 frame behind the part's visual position for that frame
Also, if the model is not rendered in-world, the part's matrix will not be updated
Paperdoll rendering and other UI renderings will not affect this matrix
