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"

Crash when importing FBX scene with material name that contains slash "/"

When importing an FBX that has a material with a name that contains a slash ("/") the editor crashes.

This can be triggered by switching to the "materials" tab on the import dialogue, or, when going through the import process a crash will happen at the very end.

It is due to the import folder creation process attempting to create a directory such as "/Game/ImportFolder//Material"

 Fatal error: [File:D:\Build\++UE4+Release-4.12+Compile\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 530] 
 Attempted to create a package with name containing double slashes. PackageName: /Game/TargetImport//Acrylic1

and also the name of an asset may not contain those characters

Suggested behavior for importing from FBX would be replacing illegal characters with "_", rather than immediately crashing the application.

Alternately- an error dialogue could be provided stating that material names cannot contain those illegal characters, rather than crashing.
