Public-domain (CC0) building graphics for modders, made to fit the vanilla Factorio art style: 76 animated buildings in 26 families, most in three tiers - generators, turbines, boilers, beacons, crafters, furnaces, kilns, mining drills, tanks, pumps, labs, accumulators, roboports, radars and inserters, plus eight exotic endgame machines (hypercube compressor, singularity press, gimbal stabilizer, fusion torus, matter printer, rift drill, orbital receiver, neural vat). Animated base, glow, shadow, recipe/resource-tint and Space Age frozen layers, multiple directions, plus a small Lua library to use them from your own mod. Optional showcase machines (startup setting, off by default). License: CC0 1.0 Universal (public domain dedication). Use, modify and redistribute the graphics and code for any purpose, commercial or not, with no attribution required. All graphical design done by Claude Opus 5.5 (Anthropic's AI model), directed by trentmkelly.
Lua libraries for use by other mods and submods that are parts of a larger mod.
