But I have a simple suggestion. Definitely not foolproof, but good enough I believe.
How about:
Use a simple close-sourced Plugin to handle usage of purchased asset.
The public-build editor cannot read purchased asset but would need plugin to ‘read’ them. In this way , only epic could make these special encrypted marketplace asset and provide the
plugin already compiled.
This could be done discreetly without significant hassle to legit user.
Just my 2 cents on this issue. My assets are being pirated , but i’m not really making a big hassle of it, it’s just that I am seeing some people are really taking their marketplace sales as serious
business activity and I would love to see that continuing in benefit of the Unreal community. If the sales go , these people go.
