What you need before starting
Happy Oyster is in free early access as of April 2026. Visit [thehappyoyster.com/try-happy-oyster](/try-happy-oyster/) to request access. No download or installation required — everything runs in the browser.
Step 1: Describe your world
Open Directing Mode and write a natural-language prompt describing the scene you want. Be specific about setting, mood, lighting, and key objects. Example:
> "A misty Japanese garden at dawn with a stone bridge over a koi pond, cherry blossoms falling, warm golden light"
Happy Oyster generates the base 3D environment in seconds. The scene is fully explorable from any angle.
Step 2: Refine in Directing Mode
Once the base scene is generated, use follow-up prompts to refine it:
- Add elements: "Add a wooden bench near the pond"
- Change lighting: "Make it sunset with long shadows"
- Adjust mood: "Add light fog rolling across the water"
Every edit is persistent — the scene accumulates your changes instead of regenerating from scratch. This is the key difference from video models like Sora.
Step 3: Explore in Wandering Mode
Switch to Wandering Mode to enter the scene in first person. Walk through your creation, discover angles you did not plan, and record camera paths for export.
The geometry stays consistent between visits. You can leave, come back tomorrow, and the world is exactly as you left it.
Tips for better results
1. Start broad, then refine: Begin with a general scene description, then add details in follow-up prompts
2. Use specific materials: "Weathered stone" works better than "stone"
3. Describe lighting explicitly: Time of day and light direction have the biggest impact on mood
4. Iterate in Directing Mode first: Get the scene right before switching to Wandering Mode
5. Record multiple camera paths: Different angles tell different stories from the same world
Export and share
From Wandering Mode, record a camera path and export it as a video clip. You can also take screenshots at any point. Share directly or use the clips in your video editing workflow.
