Testing Grok 4.6, a user managed to build a complete Falcon 9 booster return sequence in a single HTML file. The simulation covers complex stages including stage separation, plasma reentry, grid-fin guidance, and the landing burn.

The entire animation is 100% procedural and runs directly in the browser. The model also handled the 2K PBR texturing, engine modeling, and generated background music perfectly synced with the camera animations.
