Realistic Trees for Unreal Engine

Trees in Realistic Style for Unreal Engine

Unreal Engine 5 imports these trees via FBX, OBJ or glTF/GLB. Enable Import Mesh LODs to keep LOD1–LOD3 from the file, or add them later in the Static Mesh Editor; convex collision arrives when hulls are named UCX_<MeshName>. Leaf materials use Masked blend, Two Sided and the Two Sided Foliage shading model, so they drop straight into Foliage Mode or PCG as instanced static meshes. Nanite handles masked materials from 5.1; keep the classic LODs for mobile.

Bark uses base colour, normal and roughness maps; leaves are alpha-tested cards that write depth, need no sorting and cast correct shadows. Separate bark and leaf materials keep draw calls predictable, and LOD1–LOD3 shed branches and cards at distance. The 14 trees run from Oak, Scots Pine, Spruce and Birch to Olive, Baobab and Dead Tree — aimed at first-person, survival and open-world projects.

About the Realistic style

Realistic models use the PBR metal/roughness workflow that glTF 2.0, Unity, Unreal, Godot and three.js read directly.

Bark: base colour, normal and roughness maps on the trunk and branches.
Leaves: alpha-tested (masked) cards with leaf-cluster textures, not alpha-blended, so they write depth, need no sorting and cast correct shadows.
Bark and leaves use separate materials, which keeps draw calls predictable and works well with GPU instancing.
LOD0 is the close-up mesh; LOD1–LOD3 drop branches and leaf cards, so the last level is light enough for far distances.

Best for first- and third-person games, survival, open worlds and simulators on PC and consoles. On mobile, start from LOD1 or LOD2 as the nearest level and watch overdraw from leaf cards.

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.
