Underwater in Low-poly Style for Unreal Engine

Faceted low-poly look with flat shading and vertex colours — no textures at all. Trees, foliage and rocks for Unreal Engine 5 that work with the Foliage tool from the first import. This group covers underwater plants and reef forms for seabeds, lagoons and shallow water: staghorn coral, red coral, brain coral and sea fans, plus kelp, seaweed and water lilies. Used together, they create the layered look of a reef or a sheltered lake bottom. Each model ships with LOD0 to LOD3, collision and a pivot at the base, so corals stay anchored to the seabed and do not float. Kelp and seaweed carry sway weights for gentle movement. Every seed gives a different branching shape or frond arrangement, and the models export as GLB, FBX and OBJ for Unity, Unreal Engine, Godot and Bevy. 7 game-ready models in this selection. Every model has LOD0–LOD3, collision and a pivot at the base, and each new seed gives a new variation of the same species.

About the Low-poly style

Low-poly vegetation is the cheapest style to render and to ship.

Flat shading: one normal per face gives the crisp faceted look; no normal maps.
Colour lives in vertex colours (glTF COLOR_0), so there are no textures, no UV work and almost no video memory.
Leaves are solid geometry, not alpha cards: no alpha testing and no transparent overdraw, which matters on mobile GPUs.
One material can be shared by every model in the scene, so trees batch and instance easily.
Typical budgets range from a few hundred to a couple of thousand triangles at LOD0.

A good fit for mobile, WebGL/WebGPU, VR, strategy, city builders and stylised indie games. In the engine, use a material that multiplies by vertex colour.

Using it in Unreal Engine

Unreal Engine 5 imports FBX, OBJ and glTF/GLB (through the Interchange framework).

LODs: enable Import Mesh LODs for an FBX that contains LOD meshes, or add LOD1–LOD3 later in the Static Mesh Editor via LOD Import.
Custom collision: FBX meshes named UCX_<MeshName> are imported as convex collision.
Leaf materials: Blend Mode Masked, Two Sided, and the Two Sided Foliage shading model for light passing through leaves.
Place trees with Foliage Mode or the PCG framework; foliage is rendered as instanced static meshes.
Nanite supports masked materials since UE 5.1. Keep the classic LODs for mobile and other non-Nanite targets.
