CMA Graphics: 76 free machine sprites for Factorio 2.0

76 animated buildings in 26 families, made to sit naturally next to the vanilla art, released as
CC0 (public domain). Use them in your mod, change them, sell the mod, don't credit anyone. It's
all fine.

This is a graphics library for modders. On its own it adds nothing to your game, unless you turn
on the showcase machines (see below).

What's inside

Most families come in three tiers:
- Mk1 is industrial: riveted, rusty, hazard-striped.
- Mk2 is engineered: clean white panels, teal accents.
- Mk3 is post-game: dark, glowing, a little bit impossible.

The machines are deliberately somewhat vague about what they do. Give them a name, a recipe category and stats in your own mod.

The endgame set is machines that are clearly doing something, though nobody is quite sure what:
- a wireframe hypercube turning inside out through itself;
- a black sphere in a lensing shell, orbited by an accretion disc;
- three gimbal rings holding one point of light perfectly still;
- a sheet of light printing an object out of its own hologram;
- glowing filaments pulsing in a vat of something dark.

See the gallery for every tier.

Every machine ships with

• Seamless animation loops: 32 frames for most machines, some 16–64. All rendered at high resolution (64 px per tile).
• A glow layer (additive, draw_as_glow) so machines light up at night. Most glows are neutral white, so you can tint them per module, recipe or resource.
• Shadows and an idle frame.
• Space Age frozen patches for every machine type that supports freezing.
• Recipe-tint layers on several crafters: liquids, workpieces, holograms and accretion discs take the recipe's colour.
• Resource-tint layers on the mining drills: the ore, and the rift, take the resource's colour.
• Multiple directions where the type allows rotation (4-way crafters, drills, boilers and pumps; horizontal and vertical turbines).
• Special cases handled:
• a 64-direction radar;
• separate inserter arm sprites;
• roboport door animations;
• accumulator charge and discharge;
• a storage tank whose sight glass shows the real fluid level.
• Icons at 64 px and 512 px.

Using it in your mod

Add the dependency to your info.json:

"dependencies": ["base >= 2.0", "cma-graphics >= 0.3.0"]

Then, in your data stage:

local MG = require("__cma-graphics__/lib/machine_graphics")
local G = MG("singularity-press", {variant = "mk2", animation_speed = 0.5})

my_machine.graphics_set = {
  animation = {layers = {G.base, G.shadow}},
  working_visualisations = {
    {apply_recipe_tint = "primary", animation = G.tint},
    {fadeout = true, animation = G.emission},
  },
  frozen_patch = G.frozen,
}
my_machine.icon = G.icon

MG(name, {variant, direction, animation_speed, scale}) returns ready-made layers:
- working: base, glow and shadow;
- idle: the idle frame and shadow;
- base, emission, shadow: the individual layers;
- frozen: the Space Age frozen patch;
- tint: the recipe or resource tint layer;
- icon: the item icon.

The included README lists what each machine ships with (layers, directions, tints) and has worked
examples. The showcase prototypes in prototypes/ show how each one is wired up: generators,
beacons, labs, drills, roboports, radars and more.

If you'd rather wire things up yourself, the raw sheets are in graphics/entity/<machine>/, with
their exact sizes and shifts in lib/sprites/<machine>.lua.

Showcase machines

Want to see them in-game first? Turn on the startup setting Showcase machines (it's off by
default). It adds every machine as a working building, with free recipes in its own crafting tab:
- crafters, furnaces, drills, labs, beacons and pumps;
- a reactor that burns uranium fuel cells;
- an orbital receiver that simply produces power.

Their balance is a sketch, not a design. The showcase is meant for previewing the art.
