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"

Child BP does not inhering parent's value correctly

Hi everyone,

I seem to have encountered a bug in 4.17 when sometimes the default value of a variable in a parent blueprint is not passed to its children. Instead, the child gets a 0 value on that variable. I've seen it happen twice in my current project and the workaround for now is to simply override the value at the child blueprint.

A quick video showing what I mean:

Hope this is in Epic's radar already.

Thanks!

Hello CoquiGames,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?

  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?

  3. Could you provide screen shots of any settings/blueprints that maybe involved with this issue(in the case of available repro)?

Hi Rudy,

Thank you for following up! I will try to reproduce it in a clean BP project and report back.

Thanks!

Hi Rudy,

I have tried to reproduce the bug on a clean project and I havent been able to. If it helps, I think this happens when I make a change to a parent BP, compile it, but then the children dont need to compile (sometimes you see that you have to save all children and sometimes you dont).

I would close this thread for now, as this bug seems quite rare. If I am able to reproduce in the future, I'll try to contact you directly, if you dont mind :)
