Undopia 3D Bars Resource Pack replaces flat iron bars with detailed three-dimensional models. Vanilla iron bars normally look completely flat like paper when you view them from the side. This pack adds thickness and volume to each rod so they look like solid metal pieces. Stronghold hallways, prison cells, and window grates gain a much heavier look without changing the default game style.
