Easy Sea Wave

Stylized low-poly islands, beaches and animated waves in one click, with twinkling sun glints, swimming fish and a looping GLB export.

Draw a shoreline curve and Easy Sea Wave builds a cute low-poly coast around it: sand, grass, foam waves rolling up the beach, wet sand, a shallow-to-deep sea, glittering sparkles and little fish swimming in circles. Everything is animated as a seamless loop and exports to a single GLB, ready for games, web viewers and mobile apps.

No textures, no node setup, no simulation baking. Just curves, sliders and a stylized look.

Highlights

• One click to a finished scene with Add Island Curve or Add Beach Curve
• Works with any curve you draw. A closed curve gives an island, an open curve gives a beach
• Live updates. After the first Generate, every slider changes the result instantly
• Seamless looping animation, with adjustable loop length
• Built-in sparkles and fish, or use your own models
• One-click GLB export with all animation merged into one clip

Features

Shoreline-driven workflow

• Use a Bezier or poly curve as the shoreline
• Closed curve = island with sea on the outside
• Open curve = beach strip with sea on the right of the curve direction
• Flip Sea Side turns an island into a lagoon or lake
• Adjustable segment count and a random seed for reproducible results

Island and beach land

• Sand and grass with a smooth gradient between them
• Controls for land height, beach width, grass blend and seabed depth
• Optional hill in the middle of an island, with its own height and width
• Open beaches get a grass area behind the sand
• Colors are stored as vertex colors, so no textures are needed

Animated waves

• 1 to 6 wave layers, each with foam, a translucent shallow-water wash and a scalloped edge
• Controls for start distance, spacing, max reach, foam width, wash width and wash opacity
• Scallop size and depth, plus edge variation so the waterline never looks mechanical
• A wet sand layer darkens as each wave reaches up the beach
• Timing controls: Loop Frames, Advance Time, Rest Time and Phase Spread

Sea surface

• Shallow-to-deep color gradient with soft transparency near the shore
• Adjustable sea width and colors

Sun glints (sparkles)

• Star-shaped glints that flash, drift slowly across the water and vanish
• Controls for count (up to 5000), size, flash time, drift distance and twinkle groups
• Use your own sparkle model. It keeps its own materials and vertex colors

Swimming fish

• Low-poly fish that swim in loops around the sea, with tail-wag animation
• Controls for count (up to 30), size, swim range, height above the water and color variety
• Every fish gets its own size, path, direction and tint
• Use your own fish model (head pointing along +X). It is scaled automatically and keeps its own look

One-click GLB export

• Exports the island, waves, wet sand, sea, sparkles and fish
• Wave, sparkle and fish animation is merged into one looping animation clip
• Animation name is customizable (default: Waves_loop)
• Uses Blender’s built-in glTF 2.0 exporter

Convenience

• Reset buttons for every section, plus a global reset
• A Clear button that removes the generated objects and the curve
• Full undo support
• Error messages appear in the panel instead of failing silently

Quick Start

1. Install and enable the add-on, then open N Panel → Easy Wave.
2. Click Add Island Curve or Add Beach Curve. The scene is generated at the 3D cursor.
3. Press Play to see the loop, and tweak any slider to update it live.
4. To use your own shape, draw a curve, select it and press Generate.
5. Click Export GLB.

Requirements

• Blender 5.2 or newer
• The built-in Import-Export: glTF 2.0 add-on must be enabled (it is by default)
