Duplicate with Lightmap v1.1 is a Unity plugin that solves the issue of duplicated lightmapped objects losing their lightmap data in newer Unity versions. In older Unity versions, duplicating baked lightmapped objects preserved their lightmaps, saving texture memory and avoiding the need for frequent rebaking. With this plugin, users can duplicate lightmapped objects using CTRL + SHIFT + D, and the duplicates retain the original lightmap information. When the original GameObject is rebaked, all duplicates automatically update to reflect the new lightmap data, ensuring consistency and reducing asset redundancy.
