I’m trying to learn Three.js raycaster. I have simple gltf model and I’m trying detect objects in gltf model. For example i want to click house in gltf model and my camera zooming to house. But my raycaster only detect gltf model, not house. Anybody can help me thank you.

Can you try without ‘true’ parameter to detect child objects.

const intersects = rayCaster.intersectObjects(model,true);

const intersects = rayCaster.intersectObjects(model);
