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"

Custom Trace Channel don't work.

If create custom trace channel in Project Settings with default Ignore behaviour, it will won't work with Line Trace By Channel in Blueprint. Despite the ignore config trace will be blocked. This problem isn't pesented in UE 4.10, but in UE 4.11 is sometimes works, sometimes (usually, in most cases) - trace will be blocked anyway.

I seem to have the same Problem in 4.11.2. Added a custom trace channel with Ignore as Default. Set it to only block on my floor tiles but my "get hit result under cursor by channel" still gets blocked by other objects (walls and so on).

Anyone found a solution for this?

I've set custom MyTrace channel (ignore by default), and used it in LineTraceByChannel node.

I've also set blueprint meshes that I want to be visible to custom collision, then checked "block" for MyTrace channel...

2 blueprints are working, 3rd is not even everything is set the same. Can't figure out why is my chair still ignoring this channel, even glass and floor are blocking ok.
