Island Painter lets you paint islands, cliffs and terrain directly in the Unreal Editor using your own modular meshes. Click to raise land, Shift+Click to lower it, and the plugin picks the right piece for every tile, bends it to fit the grid and bakes the result into ordinary Static Meshes with collision. Nothing runs at runtime, your level ships with plain Static Meshes.

Make your own kit - you only need four meshes: Corner, Edge, Inner Corner and Full. Shapes are detected from the geometry and used in all four rotations, so you model each shape just once. Add as many variants as you like and every tile picks one at random or you can swap for more fitting one with Ctrl+Click.

Features:

- Paint on an organic irregular grid or a regular square grid

- Raise and lower land level by level to build stacked cliffs

- Overlay kits for paths, sand, grass, walls and more, painted on top of the terrain

- Unlimited variants per shape, picked by seed, Ctrl+Click swaps a single tile

- Pieces bend to fit irregular cells, so organic islands stay seamless

- Keeps your materials, all UV channels, vertex colors, normals and up to 8 LODs

- Bakes into Static Mesh chunks with collision and optional Nanite

- Baked meshes are saved next to the map and rebuilt next to it if the map is moved

- Works with any art style since it uses your own meshes
