Hi Ruochun, Both times with 11. previously it was 11.2, but now it is 11.8. Took me a while, but I figured the problem was the mesh ( obj file), and the code ran just fine with the previous mesh file. I have the exact same design but used a different software! I am trying to figure out that maybe the texture is being restored in obj somehow. Let me know if you have any ideas on this!
