Artifacts in renders (comparison included)

[masonspappy]

Attached image shows side-by-side comparison of image rendered in T3 and T4.
The T4 version seems to be a significant improvement over T3,  but there are artifacts  on the girl OBJ in the T4 version.
After reading the technical information in the forum I couldn't see anything that I thought speaks to this particular problem, or anything that might be done to correct it.
If anyone has any suggestions I would really appreciate hearing them.

I have had the same thing on a couple of renders, don't know what it is or how to fix it. It almost looks like really tiny displacement artifacts.    I forgot to mention that it was on imported .obj models also.

Exactly.

Did a high-quality render (1920x1080) last night  ( See image snippet below) , and pulled the camera back and can no longer see the artifacts. Don't know if that because the artifacts disappear during a Hi-Q render, or they simply can't be seen from a distance. Think I'll move camera up close again and re-render in Hi-Q and see what happens.

I rendered at 2K closeup and got this.............

The other render was basically the same.

I haven't been able to reproduce any artifacts like this. Can you send us a simplified scene that produces this error?

I spoke too soon. I've got something similar which I can work with.
