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"

Post Process Anim Blueprint cannot be cleared

  1. Set a post process animation blueprint for a skeletal mesh.

  2. Try to clear it, by picking again.

  3. Note that it hasn't cleared.

It would be nice if this could be fixed in the next update, not in 4.15. Since it basically breaks any character with Anim Blueprint Postprocess assigned. Unless you are fine with running the AnimBP twice on your character

Hi unit23,

Hotfixes are typically reserved for major regressions and crashes.

The workaround would be to import a copy of your skeletal mesh (using the original skeleton), then delete the "broken" mesh. When you delete it, you can use the "Replace References" option in the delete window to replace all references with the new copy.

If you really need the fix, you can integrate it into your build of the engine from this section of code.

Specifically this section:

     else if(!AssetData.IsValid())
      {
          // Asset data is not valid so clear the result
          UObject* Value = nullptr;
          BlueprintProperty->SetValue(Value);
      }
