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"

Hello Kurylo3d,

The old file comes from Saved/Config/Windows/Engine.ini that was copied along other content from project-to-convert. The ini contains paths for old location. If you suppress copying this folder everything seems to work fine as Saved/Config ini's are rebuilt by the UE4. The same paths will be wrong if you switch Engine version, as some of them are relative to the Engine directory. It may be worth to check if this is solved during Engine switch.

Please check to make sure that your project is correctly referencing this mesh.

Hey so, If the other post is the one you are trying to get an answer for, and this is a duplicate I will be marking it as answered just so there is no confusion.
