Gltf physics in react three fiber

I’m learning three.js. I downloaded a gltf model, convert it to jsx using @react-three/gltfjsx. I put it in Scene inside . But the boxes are falling through this model

Gltfjsx isn’t physics library, it just converts gltf model in jsx component for easy access of each mesh. You’ll have to use some physics library, if you’re using react three fiber, check out the React three cannon.
Edit : you’re using physics library, sorry didn’t see it. You’ll have to convert your model in physics cannon mesh, I think you can convert gltf model using Convex polyhedron
