The problem of ray selection of mesh corresponding material in threejs
I have a model, only one mesh, and material is an array in mesh with 4 ShaderMaterial.The data structure of the model object，Position of material mark point
I want to click the mesh to get the material in the corresponding position, and use Raycaster to get the intersect object. I want to find the corresponding material in the object through the face.materialIndex.How do I get the right material? intersect data

If you have a specific materialIndex, you can get the corresponding material object like so:
const material = mesh.material[ materialIndex ];
As stated in the documentation when using multiple materials per mesh, Mesh.material becomes an array of materials.

I know what you mean. Now, the problem is that I get materialIndex from a ray, and I click anywhere on the model, and the returned materialIndex is 0, and it doesn't return the materialIndex that I want, I don't know what the problem is.

Thank you. When I wanted to create an example, I found that the problem with the GLTFLoader version had been solved.
