That first image looks wrong too…would it be possible to get the model?

Yes

The first image give acceptable result when use it for displacement

I found the problem, and I have a fix ready for this. Essentially I’m writing the normal pass more often than necessary. You can follow here: RH-63236 Normal channel looks incorrect
