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"

Still have same issue At 4.14.. Still...

Qukla,

Have you tried migrating your project over to a new, clean project in either 4.13.2 or 4.14.0? If so, what was your result? Did you try recreating your blueprints as well?

avatar image 如果爱 Dec 11 '16 at 04:17 AM

I just encounter the same problem,and i googled it , i try to use a lot of methods, but it has not been resolved. at last , i renamed the struct. and build the project again. it was sucessed! you can try it.

avatar image mikeyj21 Aug 21 '17 at 07:47 PM

This article really helped me; six months in to a project, i was close to smashing my pc/monitor/head to bits.

This pointed me to renaming my structures one-by-one until it suddenly started to package. What didn't help was the error talked about an unknown struct I didn't even have! There seems to be a problem with Unreal when you refactor which causes this....

Anyway, thanks to this post I am happy again (with just a sore head!)

:)

Same Error in 4.18.1 ... A Fix in UE4 would be nice. Something to tidy up structs. I ran often in problems when structs are edited in BPs on compiling and on problems like this thread.

avatar image HitEmUp Oct 17 '18 at 07:59 PM

This is a huge problem... Can a Staff create a bug report. So it get fixed in the next releases. This bug is known since UE 4.8 and still here 10-17-2018 UE 4.21

The structs need to save and recompile! Or change the name and save and recompile. But it seems that every ref. also need a save and recompile, too.

i get this error occasionally... i just experienced it these days back.. here was my fix: I went into the struct, opened it, saved it, closed it.. went into the file that was using that struct (in my case just a save file, even though it is referenced by many other bp's just going into the original save file that struct is saved in fixes this bug)... so open that save file, click on the struct variable, compile the save file, close it... boom project now builds successfully... its not the first time it happened to me nor will it probably be the last.. it is weird but these fixes work...

This solves it for me. Happens whenever I edit a structure associated with a save game.

I renamed the struct and all refs got updated. Then I built the project before package and worked.

Note: my problem was in the editor not visual studio

Yes, it works. But a Fix in UE4 would be nice that correct Struct handling. I have to rename my struct frequently. And sometimes also have to delete "Intermediate" and fix other things which are messes up after struct changes.

Hey Qukla,

There are a lot of warnings and errors within your project. Please focus on correcting the errors first. The errors below seem to indicate that these structures are unknown.

Did you update your project from an older version? Did you adjust, or restructure any of your structures within your project?

Newest thanks a lot for your answer. I just solve the problem : )

I was migrate all maps to new empty project. Then i realized all the struct errors begin after migrate.

In Bluepirnts which gives errors, i delete all sturct variables then add then same ones again. And it fix the errors.

after few other fixes, Now i have 0 Errors and 300 warnings. : ) I am working on that wornings as well ^^

Thanks again

Thank you very much for this comment, it saved my project.

I deleted the struct variables in 3 blueprints then added them again and it magically works.

Thanks :)

How do you fix them? I've been getting theses since updating to 4.11. I don't have time to rebuild a year's worth of Blueprints.

For anyone still running into this: I got this today in 4.13, but I was able to fix the cook error by just renaming the variable instead of removing and re-adding it to the classes that reference it (much easier than having to fix up every reference afterward).

avatar image GameKittens Aug 24 '17 at 03:48 PM

I had this issue too. Fixed with the renaming trick mentionned above.

I noticed something else in 4.17 : when editing the structs, i click save button, all variables types are changed to base types struct/int/string, etc. A vector and a transform were changed to struct. Then i close this window, launch the game, and then open the struct again, it goes back to normal. Opening the struct without launching the game still displays the wrong types on variables.

I was getting the same issue in 4.19.0. The trick of renaming the struct variable, then immediately (no compile needed) renaming it back to what is was, then recompiling the blueprint did the trick! Well, then after doing it all, I exited and reopened the editor. And for good measure, fixed up redirectors. The last two sometimes fixing problems (warning---the very last, fixing up redirectors, has broken things for me in the past! esp. materials calling material functions that moved)

avatar image Postalh Oct 24 '16 at 01:42 PM

I ran into this issue and fixed it as suggested by renaming a bunch of variables. Project was updated from 4.12. Shouldn't there be some sort of "blueprint clean" functionality to address these inconsistencies that can appear. Nothing about the logic in my game has changed.

I ran into a similar error and fixed by explicitly adding the directory containing the data asset to the packaging list of directories to include.
