FName::IsValidGroupName
#include "UObject/NameTypes.h"
Access: public
Specifiers: const
Description
Validates that this FName is legal for use as a package or group name. Package names permit forward-slashes as path separators; group names do not.
Caveats & Gotchas
- • Despite the method name, the default (bIsGroupName=false) checks package name legality — not group legality. Pass true explicitly when validating group names to avoid checking the wrong rule set.
- • This method validates string content only; it does not verify that the corresponding package actually exists on disk or in the asset registry.
