About this project
What does Underwater Bubbles add?

Underwater Bubbles lets you create an underwater haven inside a breathable bubble. Combine full spheres and domes to shape connected spaces for ocean homes, submerged gardens, research stations, and fantasy builds. Choose between Classic and Rainbow appearances, then adjust transparency to suit the surrounding water and the view from inside. Live placement previews help you position each bubble before committing to a layout. The included Your Underwater Haven 101 guide introduces the system, giving you a starting point for building beneath the surface while keeping the surrounding ocean part of the scene
