Any other value will be ignored and the default drawing will be applied. | :heavy_check_mark: | | | |

| linkThreeObjectExtend | bool, string or func | false | Link object accessor function, attribute or a boolean value for whether to replace the default link when using a custom linkThreeObject (false) or to extend it (true). | | :heavy_check_mark: | :heavy_check_mark: | :heavy_check_mark: |
