Coral Reef Generator builds corals, anemones, sponges and complete reef patches in one click, right inside Blender. Pick a design from the sidebar and a finished, colored model appears at the 3D cursor. Every design stays editable: change size, branch count, spread, thickness, colors or the seed and the model rebuilds live.

It covers the real reef types you need for underwater scenes, aquariums and games, from fine staghorn thickets and broad elkhorn antlers to brain corals with meandering grooves, mushroom corals with radial septa, sea fans and swaying anemones.

What you can make

• Branching corals: staghorn, purple and blue Acropora, elkhorn
• Table and plate corals, lettuce coral tiers
• Brain, pillar, mushroom and bubble corals
• Sea fans (gorgonians), tree soft coral and leather coral
• Sea anemones, carpet anemones and bubble-tip anemones
• Barrel, tube and vase sponges
• Whole reef patches: rippled sand bed, coral rubble and a spaced mix of corals
