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"

ERROR: System.ArgumentException: Empty path fragment in staged filesystem reference

After the 4.18 update I'm getting this annoying error when packaging. Did anyone else run into this problem?

Dunno if this helps!? I just had this issue after an upgrade to 4.17 and it turned out to be a blank array entry in my Project Settings > Packaging > 'Directories to never cook'. The error disappeared and built successfully as soon as I deleted the entry.alt text

You are a legend, I had one in "additional asset directories to cook".

How on earth did you find that!? I spent days trying to figure out what was going on. Thanks!!!

Silly me quickly checked for Directories Never To Cook a few days ago, but skipped looking at "Additional Asset Directories to Cook." My problem was also a blank array entry in "Additional Asset Directories to Cook" under Project Settings > Packaging.
