Creature Builder+

1. Back up your save and close No Man’s Sky.
2. Open NMSE, load your save, and open Companions.
3. Import the downloaded .nmspet into a free companion slot, then save.
4. Open NMS and summon your pet. Check its body parts and colors in-game.

To edit an existing companion, export that pet from NMSE first and use Import pet here. Work happens in your browser; pet files are not uploaded. A plain JSON export can also be used with a compatible editor’s raw companion view.

The catalog targets NMS 6.45.1 using NMSE data and locally extracted game geometry checked September 5, 2026. All 86 catalog entries have geometry previews. Expedition 23’s Diplodocus uses its own game model and animations, added September 19, 2026. Flocks show one representative member; ground creatures show a representative form. Pet animation posing is available for 84 entries: select a clip, play or pause it, or drag the pose slider. Poses only affect the preview. Protoroller and Drill have procedural rolling and spinning preview loops; these are not extracted game clips. Exports have not been tested inside a running game. Some special or aquatic entries may not behave as summonable companions. Original game diffuse textures and surface materials are shown. Seed-generated palettes, biome lighting, and special shader effects are not reproduced exactly.
