UEditorValidatorBase

The EditorValidatorBase is a class which verifies that an asset meets a specific ruleset.

API > API/Plugins > API/Plugins/DataValidation

The EditorValidatorBase is a class which verifies that an asset meets a specific ruleset. It should be used when checking engine-level classes, as UObject::IsDataValid requires overriding the base class. You can create project-specific version of the validator base, with custom logging and enabled logic.

C++ and Blueprint validators will be gathered on editor start, while python validators need to register themselves
