Node Copyright

V8 Infinite

Hello, I have a question regarding an Iray node used in Daz 3D.

It's called: "Nylon Base Material (MDL)"

This node is present on several products and with different sellers, I contacted sellers and no response.

I analyzed its structure, and it's the same for everyone, the same tiles in the same places, the same connectors etc.

I browsed forums, Deviantart, Artstation, installed the Nvidia V-Materials libraries (including the last one) and it is not present anywhere...

I asked everywhere to find out who created it, is it open source?, free of rights? Was it copied and duplicated? I don't know anything about it...

I come to ask my question here to find out more, who is the creator of this node?

Can I use it while being in compliance with lifetime copyright obligations?

THANKS.
