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"

Sound Cues Randomly not working

We're having a consistent issue with soundcues not working. It appears to be completely random.

Sometimes the full soundcue shows a flow through the nodes, but no sound is playing. Sometimes you can play individual nodes but output doesnt work. Sometimes playing the full cue works, and individual nodes doesnt play. Sometimes you can copy all the nodes from a non-working cue, to a new one, and everything works. And then when you restart the editor it's random if that cue is then working.

It seems to be completely broken, and it makes it impossible for us to work on the sound for the game.

What could be the issue here, and how do we solve it?

Hey Fred-3DR,

Could you provide me with a screenshot of you Sound Cue set ups for a few of the sounds you are using?

There is a known and reported issue with certain nodes like the 'Concatenator' causing sound cues not to function. You wouldn't happen to be using this node in the sounds you are experiencing issues with, would you?

Edit: As MinusKelvin stated, I meant the 'Attenuation' node.

Thank you,

Andrew Hurley

I believe Andrew may be referring to sound attenuation nodes since I recently fixed an issue that is getting hot-fixed in 4.11.2 which might be the likely cause of this.

Hi Andrew!

We're only using Attenuation and Modulator nodes, so the cues are very simple. But they seem to break randomly.

MinusKelvin, is there a Hotfix we can apply ourselves? I found this thread:

Yes, the attenuation nodes are the issue. The hotfix is not out yet, but the fix I described in that thread should work.
