Existing mesh/Clean uv's- new from uvcheck error

ZBrush Usage Questions
#1

Hey guys I am working with an existing asset that has clean uv’s. They are within the uv space and not touching the border, and dont have any overlapping. The object is a hand, and I am getting some diagonal red edge indicators on a couple of the fingers even though there are no seams going across the area. Using new from uv map doesn’t produce and discontinuity of color, so I am having trouble figuring out what is causing the red edges when I do new from uv check.

My exported map is having issues in these areas.

thanks for any help or suggestions.

So it was a vert touching the uv space border, outside apps packed the uv’s, but Zbrush didn’t like the location.

I am still having an issue with Displacement maps showing some seams when rendered in Arnold/Softimage.

Open to suggestions on how to fix that, I used multimap exporter and a variety of settings, nothing working so far. Not a big line type seam, just an obvious transition along the seam.

thanks
