I am looking at the big box on the bottom right with the word female above it and the two knobs.   Although the lines might be as well.  Without looking at the file its hard to tell.  Normal maps will cause this (well bump maps) and it might not show up until render.    

What your showing is not the same and looks like its from your graphics card. but without looking at the rest of things its hard to tell. 

Again a lot of this is just guessing because without being next to the person looking at the file and his pc its just a lot of guesswork.  Can't see the diffuse or albedo map or whatever (again they like to shuffle wording around although diffuse can include shadows baked in) or the normal maps so it might be entirely texture based or.. your pc or.. a combination of the two orr a bug ^^.

Well I'm lost .... I'm not sure if we're all on the same page really ??
Yan said:. " ... to wit, the grey colour of the panel is showing rather nasty banding that makes it look like corrugated cardboard... "
I thought that meant the part in my posting #pic 1

the banding and the box (the box kinda pushed it over the edge for me.. which is why i opened up my keyboard) are not showing any colour with the exception of some shadow greyish and it looks bevelled.  I see colour in yours.    That's the difference there.  In his is just looking like err texture.     Its hard to explain (sorry) Sad

No need to apologise urbanlamb  Smile  - it's purely a misunderstandaing  .... it comes down to what Yan means by 'Panel'
ie: the entire photo OR a smaller part in it.
But there IS the same pattern throughout the entire pic that I'm seeing (when the 'levels' are tweaked to emphasize the pattern) .....

the bands are the same regardless of lighting and shadows etc etc so I am fairly certain this is texture based.    (I could be wrong though) 
Yours looks like its all from your card.    There is also inside iclone an ambient occlusion layer which is created from your card not the texture but.. I dont see anything interfering with the problem with I see.     (although I see two but we wont go there)
 ..and this is why critiquing on a forum with such a diverse community is probably not a good thing hehe.

I just realized I had an 'embedded' colour profile which made the image darker... this should show the "Resolve deband" improvement a little better.https://forum.reallusion.com/uploads/images/c5f66e22-fe81-4159-911a-31ca.png

To illustrate the result of using Resolve's "debanding" plugin...  of course, the better solution is that the cause of this artifact be fixed.

The boob thing she has happening in that photo is also likely a normal map/bump map thing possibly if it the normals were painted at a higher resolution her boob problem would be gone.
