Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How secure are embedded/packaged models, textures, etc?

I have a client who is looking to build a VR project. But they are asking how secure the files will be, once packaged? Will anyone be able to dig out any of their proprietary licensed content and distribute it without their permission. It's for a museum, so they just don't want high resolution scans and textures from the art spread out publicly. Is this possible with Unreal?

Product Version: UE 4.19

First off, by default it's not secure at all. Anyone can unpack a .pak file if they have ue4. Second, I know there's a way...

I've been looking around, and I've found several answers which are... unclear at best. Maybe you can make more sense of them.

I hope this helps

Thank you! Those were interesting threads, although it does seem like it's a futile effort to encrypt data via Unreal. Sounds like anything can be decrypted on a PC. I really wish Unreal would address this.
