Hard edges on scanned model

[maxmnte]

Hi!

I don't know how to solve my problem with a scanned model (https://threedscans.com/musee-des-monuments-francais/le-transi-de-rene-de-chalon/ ).

I smoothed it, reset XForm, reset the normals, welded all the verts. What am I doing wrong? 

In the viewport it looks normal, but in the renderer I see the hard edges.

Thank you!

I could not replicate your issue.  First scan below is Arnold render of the imported .obj with no changes to model.

The next Arnold Render is with ProOptimizer set to 10%:

What are your objectives for the model?  If you want to reduce poly count did you just try to use ProOptimizer?

The imported model was uniformly scaled at 100%, and smoothing seemed fine as reflected in the above renders so why did you apply smoothing, reset XForm and weld vertices?  

Did you apply a different material by any chance?  It looks a little like maybe there is a bump map/normal map or displacement map that might be producing the rough appearance on the face.  Just a guess.

Thanks a lot for checking!

I did not find a solution at all. Today I reopened the same file and the issue is gone. I tried hours yesterday and now everything just works. Is it possible that 3ds Max needed a PC restart? I can‘t explain. Also there was no material applied. And even with Standard Surface I had the same issue.

Yes, sometimes rebooting can solve problems.  Glad it is working for you now.
