Thin instances let Babylon.js render thousands of identical meshes in a single draw call by uploading per-instance matrices to the GPU. Learn the API, trade-offs, and how to verify culling and draw calls.
Babylon.js offers clones, InstancedMesh, and thin instances for repeated geometry. Here's how they differ on picking, culling, memory, and when each one is the right call.
Decide between Babylon.js InstancedMesh and Thin Instances for large-scale identical objects. Compare CPU overhead, draw calls, picking, animation support, and memory with a concrete 50k-box example and validation steps.
