ZBrush displacement inflate in Arnold

[Anonymous]

Dear Maya community,

I have a issue with displacement map inflated my mesh.

It looks like pictures below:

1. proper mesh without displacement map

2. mesh inflated with disp map

So I double check on disp map with an isolated render view

It does look inflated....

And I know there is some similar issues and solutions I could find on google.

I did try different settings on scalar zero value, color gain, color offset,etc...

They all don't work for me.....

Then here is my ZBrush map export setting

And I did check my UVs ... I did even made two different UVs to test...

They failed again...

Please, if there anyone who can help me on this issue....

Will thank you guys so much....
