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"

Packaged game crashed on macOS when a niagara system is used

In the packaged game, it's crashed when I'm spawning a niagara system. Not instantly, it starts to work but then crash, every time. If don't use the niagara system then it's not crashing.

Any ideas where to look/what to tweak?

Error message:

 Assertion failed: LayoutConstantBufferSize == Layout->ConstantBufferSize

Specs: UE 4.21.2 (source build, no changes to the rendering part) Metal 2.0 or 2.1 (tried both, the same crash) Xcode 9.4.1 or 10.2 (both are the same)

macbook pro 13" integrated graphics (iris 6100 1536 mb)

Product Version: UE 4.21

Thank you, I know about this one, just currently I'm not sure it's a real bug – that's why I've posted it here, to check with a community in case if anyone faced the same issue.
