170 painted cartoon icons for Roblox tycoon, simulator and pet games in three sets: Military (64: tanks, jets, helicopters, supply drops, medals, ranks, ammo, radiation bombs, soldiers, HQ), Egg & Pet Simulator (48: eggs, hatching, incubators, conveyor, coins, 2x boosts, weather, mutations, chests) and Cozy Shop & Tycoon (58: cash register, shelves, mixing bowl, tables, customer portraits, toppings, slime). Every icon as PNG at 64, 128 and 256 px, plus 1024 px Roblox atlases (16 icons per upload) and a Luau module that sets ImageRectOffset for you.

Licence in one line: use them in your own games, commercial too; do not resell or re-upload them as assets. Credit is required: "Art by Gridwright" with a link to gridwright.store or this page, in your game's credits or on its store page.

What you get

• 170 icons, each centred in its square at 64, 128 and 256 px, transparent background, soft edges (painted, not pixel art). Holes such as a padlock's shackle or a trophy's handles are cut through, so they sit on any colour.
• Roblox atlases: 1024 x 1024 sheets of 16 icons (256 px cells), one theme per sheet, so a whole set is a few uploads.
• GridwrightPaintedIcons.lua: paste your atlas ids once, then Icons.apply(button, "military_tank"). Compiled and run with the official Luau tools (not inside Studio).
• icons.json with every name, theme, file and rect, and contact sheets with every name.

How it was made

We painted these icons with Google Gemini, an AI image generator, for our own Roblox games, as sheets of icons on white. Our own Python code then cut each one out, removed the bits of neighbouring icons, cut the holes through, centred and sized it, and built the atlases, the module and the JSON. They are AI-generated pictures, and the page's AI disclosure says so. The military set was painted at about 135 px, so its 256 px files are scaled up about 1.8x and 128 px is its sharpest size; the other two sets were painted at about 200-210 px and scaled up about 1.2x.
