Build reefs and sunken treasures with 20 low poly seabed models: kelp, seaweed, seagrass, anemone, staghorn, brain and table corals, sea fan, tube sponge, seashells, starfish, sea urchin, giant clam, rock, rock arch, pebbles, treasure chest, anchor, amphorae and a shipwreck. 4 levels of detail and 2 colour variants each; seaweed, anemones and sea fans sway in the current.

KEY FEATURES

• Current shader for Built-in and URP: slow back and forth, waves rising along the blades
• Mossy variants of rocks and wreck props by texture swap, bleached coral, colour sets
• Demo scene with underwater fog and lighting
• 4 levels of detail per model, 80 to 13 044 triangles, with ready-made LOD Group prefabs
• 2 colour variants per model (40 in total) by texture swap: one material, one 256x128 texture, one draw call per model
• PLUS a Realistic PBR version of every model (880 to 5 872 triangles, 2048x2048 albedo, normal and mask maps per colour): low poly and realistic in one pack
• One-click setup for Built-in, URP and HDRP: materials, prefabs and a demo scene
• Real-world scale (1 unit = 1 m), clean pivots, English names
• FBX and glTF 2.0 files, guides for Unity, Unreal Engine, Godot, Blender and the web

MODELSKelp, Seaweed, Seagrass, Sea Anemone, Staghorn Coral, Brain Coral, Table Coral, Sea Fan, Tube Sponge, Seashells, Starfish, Sea Urchin, Giant Clam, Rock, Rock Arch, Pebbles, Treasure Chest, Anchor, Amphorae, Shipwreck

DETAIL LEVELSLow and Medium are simple volumes; High and Ultra are built further, not just smoothed: ruffled blade edges, barnacle colonies, rock strata and cracks, coral polyps, brain coral grooves, sea fan mesh, urchin spine tips, clam scales, separate planks, treasure coins, anchor chain.

Documentation included (Markdown and HTML), with setup, animation, colour and engine guides.
