gsteigert / Export Groups.lua

Created November 1, 2021 15:17

An Aseprite script to ease exporting a bunch of layers and groups into packed sprite sheets (a.k.a. texture atlases).

	-- This script will:
	-- (1) Flatten each group into a layer;
	-- (2) Invoke the 'export sprite sheet' command;
	-- (3) Undo the changes.
	--
	-- v1.0: Initial version.
