I got a problem when using aicurvature node. In my case concave mode is working well but convex mode is doing nothing. I have also attached file so please check it and suggest me what to do next.

I also used same method but it did not worked for me. and if I make a cube and assign same material it is working.And also if I export model and import it in another file it is working but it is not possible for me because i worked a lot in the file.
