Any way of serializing Blender cycles materials data? I am searching of ways to serialize Blender Cycles materials to files using Python. But as of now I've found no such ways.

Maybe by writing the data of the materials to files but how can I do that? Even the slightest of contributions are appreciated.

If only there was a way to serialize materials to JSON/Binary/XML.

Perhaps someone here can lead me to light.

Maybe in the way Blender stores the materials?
There is the rna_xml module, which produces pretty verbose xml

from rna_xml import rna2xml

rna2xml(root_node="MyRootName",
        root_rna=bpy.data.materials['Material'].node_tree)


produces (not full output).  There is also an rna2xml routine.  To output to a file use rna2xml(fw=f.write, ...) where f is a file.

&lt;MyRootName&gt;
