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"

UE4.7 Cannot recreate a widget anim with the same name after delete

If you create a widget animation, delete it, and then later try to recreate it, it gives a duplicate name error.

Steps to repro:

Create a new widget blueprint.

Add an empty animation, called "New Anim"

Select this animation and delete it.

Add a new animation and try to give it the same name, "New Anim" it will give you an error saying the animation already exists.

Even if you save and compile you will still get this error. It requires a full shutdown of UE and a restart before you can reuse the old name.

Hi Furroy,

This is a known issue with asset names. UE4 keeps a cache of names that have been used in that session which does not clear until the engine had been restarted. This will also occur with any .uasset file or custom event node for instance. Our developers are aware of the problems this may cause and are working on a solution.
