Gold key free 3D model & sprite sheet

A chunky gold key with a round bow, a collared shaft and a bit with two bevelled teeth. The sprites rendered by Pixor show it spinning in place, so the ring opens up and narrows to a line as it turns. It is sized to read clearly at 32 pixels, even in a busy dungeon room.

The bow is a torus, the bit is shaped with a Bevel modifier so its edges catch the light, and all the parts are merged into one object at the end. That single mesh keeps the outline clean when Pixor draws it. The spin is procedural and added at render time.

Keys drive the oldest loop in game design: find the key, open the door. Use it in top-down dungeon crawlers, puzzle rooms and metroidvanias, show it in an inventory slot, or freeze a frame for a HUD counter of keys held. It shares the Gold material with the coin, so the two look like they belong to the same world.

To make a boss key or colour-coded keys, copy the Gold material, tint it red, blue or silver, and render each version. The obvious partners are the dungeon door and the treasure chest, both of which open with their own clips.
