Batch UV Tools is an add-on that provides operators for managing UV layers across multiple objects simultaneously. It includes functions to set or create an active UV map, delete maps, and set the active render map for all selected objects at once. Additional tools allow users to copy uniquely named UV channels across selections, synchronize the order of layers to match an active object, and move layers up or down the stack. The tool is particularly useful for preparing complex scenes for workflows like lightmapping.
