Not sure about this, but I assume if the Renderfarm HAS the copyrighted object, then it will work? If true, I wonder if it's possible Frederic posts a list of objects he currently HAS, and if a copy protected object does not appear on the list, the USER could be billed a percentage of the purchase price for the first time. This seems fair, but does have the bad effect of creating a more manual mode for a time. Perhaps it's just a case-by-case system.

I understand why C3D has an optional copy-protected scheme for sold objects. But for Smart Growth vegetation, it is NOT an option as all of them are copy-protected.

Frederic, I wonder if you were to contact someone in charge at C3D, if they might cut you a deal on the Smart Growth plants? It seems like it's in the best interest of Vue to have a great Renderfarm system like you've designed? It really is very impressive! :-)

Another idea would be to have Vue create a 'special' version of the network renderer for Renderfarms, with appropriate license terms, which does not check for copy protection. I don't see how this could create a problem as people still need to have a valid license in order to build the original scene.

But first, a way is needed (Python) to evaluate a scene and report on all copy protected textures and objects in it.
