# Details Customisation * SplineComponentDetails.cpp auto adds the Spline Meta Data to the "Selected Points" Category,\ including Details Customisation like FWaterSplineMetadataDetails. * It involves a USplineMetadataDetailsFactoryBase class and a ISplineMetadataDetails class. * The spline component details calls iterates through all USplineMetadataDetailsFactoryBase and calls GetMetadataClass() to determine the correct details customisation (it's not registered like normal details customisations). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
