Share 'Loading .mxm files'

Hi! Thanx Hannes for this great plugin!I'm pretty new in rendering with maxwell and I wonder if it's possible to load directly a .mxm file in scarab? Or do we have to recreate each material from the .png or .jpeg layers? There are a lot of materials (.mxm) without png or jpeg layers in the default library and I don't know how to do to use them in grasshopper...Thank you very much Julien
