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"

I get a handful of warnings and then these errors. I have compiled the project from in the editor, rebuilt the source, and compiled these specific blueprints. None of my fixes worked.

I'd really like to nativize these, since they are my most complex blueprints. Any ideas?

I'll also add that i was able to nativize my gamestate. The objects that did fail are all actors.

After a lot more googling, it turns out that this is a nativization issue. Enums and select nodes cause fatal errors, nativized bp's that reference non nativized seem to have issues, compiling certain ones (as seen above) just fails...

It'd be REALLY cool to see some more love invested in nativization. There's a lot of folks that need to be a jack of all trades with their projects, not having to learn code (on top of shaders, ui design, replication, game design, level design, lighting, particles etc) is basically essential.

Anyway, RIP blueprint nativization in larger projects. :/

Edit: To be fair, some of the limitations are listed here: https://docs.unrealengine.com/en-US/Engine/Blueprints/TechnicalGuide/NativizingBlueprints/Advanced

Some of the major roadblocks are: Blueprint generated classes, BP Enums, BP Structs

The majority of any larger projects will have one, if not all of the above. :/
