In regard to the protection of blueprints and materials, those graphs have the ability to collapse selected nodes to functions or macros. That would be sufficient (minimal and unintrusive) protection for me if those collapsed nodes could remain locked and not viewable with a double-click to open.

What if someone need to change something in those nodes/functions and they can’t?What then?The answer is simple, refund.
I dont know about blueprints and functions but, i personally find locking materials to be absolutely ridiculous.People everyday day are releasing in the forum materials for free, i’ve been shown my stuff all the time when someone is asking.Also materials arent that hard to replicate, because basically everything is taken from released papers, at least some of the advanced stuff.And those papers are released for free, nobody is hiding them or want money for them.The rest is not that hard to figure it out.Btw these kind of stuff are so easy to share, you dont even need to pirate them, one screenshot is more than enough, thats how easy it is.Unless is something very specific like POM for instance.I just cant see why anyone will want to sell just materials without textures or models with them,it is even hared to imagine who will buy them.But maybe i’m wrong.

Unfortunately, this scheme does not protect models, sounds or textures which must be viewable in their entirety at all times.

Everything should be visible all the time.Because every project will need specific stuff and people should have the option to change, tweak, removing, adding, or whatever else may be they need.Unless is something so specific that cannot be changed in any way, just tweaking parameters, which i just cant imagine what this can be.But again maybe i’m wrong, i’m just environment artist after all.
