Realistic 3D Models for Bevy: GLB Trees & Palms

Realistic 3D Models for Bevy

Bevy's AssetServer reads GLB directly, and this set is built for it: 42 realistic models — oak, Scots pine, birch, coconut palm, saguaro — each with LOD0–LOD3, a collision mesh and a pivot at the base. Load a scene with asset_server.load(GltfAssetLabel::Scene(0).from_asset("oak.glb")) and spawn it via SceneRoot; meshes and materials stay addressable by label. FBX and OBJ need third-party crates, so stay on glTF.

Realistic here means PBR metal/roughness bark with colour, normal and roughness maps, plus alpha-tested leaf cards on a separate material — masked, so they write depth, need no sorting and cast correct shadows. Assign VisibilityRange to the LOD entities for dithered crossfade, and let shared mesh-material pairs batch and instance automatically. Colliders come from the collision mesh via Avian or bevy_rapier; the result suits survival, open-world and simulator projects on PC and console.

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 Bevy

Bevy loads glTF/GLB through the AssetServer: asset_server.load(GltfAssetLabel::Scene(0).from_asset("tree.glb")), spawned with SceneRoot; individual meshes and materials are addressable by label. FBX and OBJ need third-party crates, so GLB is the format to use.

LOD: give the LOD0–LOD3 entities a VisibilityRange (start and end margins) for distance switching with dithered crossfade — Bevy's HLOD mechanism.
Leaves: glTF alphaMode MASK becomes AlphaMode::Mask(cutoff) on StandardMaterial, and double-sided materials disable back-face culling.
Entities that share a mesh and material are batched and instanced automatically, so many tree copies stay cheap.
Collision: Bevy has no built-in physics; build a collider from the collision mesh with Avian or bevy_rapier.
