In the next weeks, I'll work on the proper support of the new Houdini 16 /mat context materials, including a new /mat Octane material builder, support /mat HDAs and subnets, etc.
Remember that SESI has said that from Houdini 16 and beyond the shop materials are deprecated. They are supported for backward compatibility, but the new Houdini material system is the /mat context.
