template<typename T> TMeshAttributesArray< typename TMeshAttributesRegisterType< T >::RefType > RegisterAttributeInternal &40;     const FName AttributeName,     const int32 NumberOfChannels,     const typename TMeshAttributesRegisterType< T >::RealAttributeType & Default,     const EMeshAttributeFlags Flags &41;

Remarks

Register a new attribute name with the given type (must be a member of the AttributeTypes tuple). If the attribute name is already registered, it will update it to use the new type, number of channels and flags.

Example of use: VertexInstanceAttributes().RegisterAttribute( "UV", 8 ); . . . TVertexInstanceAttributeArray& UV0 = VertexInstanceAttributes().GetAttributes( "UV", 0 ); UV0[ VertexInstanceID ] = FVector2f( 1.0f, 1.0f );
