MaterialsDisabledIn1st in RenderComponentCharacterDefinition lets you set materials that should be excluded from being rendered in 1st person view. Though, it only supports materials that are applied on the character model itself. I would like to have added support to also exlcude materials from HandItems and EquipemtItems. This is especially useful for helmets and masks that are equipped on the head and constantly clipping through the camera while moving etc.
