Can't use the lighting method on the mesh #2

Hi Sean,

I try to use the THREE.SpotLight and THREE.PointLight lighting effects on the mesh loaded by OBJVertexColorLoader. And can't see any lighting on the mesh. Then I modified the file "OBJVertexColorLoader.js" and change the material from "THREE.MeshBasicMaterial" to "THREE.MeshStandardMaterial". It only works on the "THREE.AmbientLight" lighting method. How can I change the file "OBJVertexColorLoader.js" to enable the lighting methods (ex: SpotLight) can work on loading mesh?

Thank you.

Best regard,

It may be that the mesh your are using needs the face or vertex normals recalculated. Are you using my cat mesh, or your own?

Hi Sean,

Thanks for your response. I used the sample "emmy3d_1.obj" and the same result happened. I found a way to solve it: add the function "geometry.computeVertexNormals();"

Best regard,
