Using it in Babylon.js
Babylon.js loads GLB through the glTF loader in @babylonjs/loaders: ImportMeshAsync (or SceneLoader.ImportMeshAsync in older code), or LoadAssetContainerAsync when you need many copies via instantiateModelsToScene.
- LOD:
lod0.addLODLevel(30, lod1),addLODLevel(80, lod2)and so on; passingnullas the mesh hides the object beyond that distance. - Thousands of trees: thin instances (
thinInstanceAddwith matrices) render in one draw call per mesh; use regularcreateInstancewhen each tree needs its own picking or logic. - Leaves: glTF MASK maps to alpha-tested PBRMaterial (
MATERIAL_ALPHATEST). - Collision mesh: set
isVisible = falseand use it withcheckCollisionsor Havok physics (PhysicsAggregatewith a MESH shape).
