I want to build a custom file format output driver.
Like the “ROP Output Diver” node.

I tried to include both ROP_Node.h & SOP_Node.h
And declare my op as a SOP node.So if I build this node, i can load it in a SOP Network.
But the ROP command cannot find it declaration.Just like the ROP_Node.h has not include to my cpp.

Anyone know how can I make it work?
Or some other way to build a ROP Output Node can be load in a SOP Network?

Please help me.
Thanks in advanced.
