A Transform's Matrix is essentially six or 9 numbers. You can simply save them as an array, read it back as an array and then instantiate the Matrix again.

Would I need to null out the transform object first before converting to a bytearray? Here is my object structure I am trying to save: Data NodeDatalist (list of nodes like an array) Node (think graph or tree vertice) Nodedata ( children nodes, parent node) Visualdata ( transform etc) Node (think graph or tree vertice) Nodedata ( children nodes, parent node) Visualdata ( rendered, transform etc) n......
