HI,i want to translate Material Network Nodes or .mtlx to the real MaterialX file or real MaterialX network.

sure there is an optin to export materials as .mtlx. but i need replace the origial arnold shaders to standard mterialX shaders. then i can use karma to render the same asset.

here is a tool "KTMaterialXTools" did this in katana Your text to link here... [github.com]

so maybe anywhere has houdini tools.
