Vray displacement with UDIM

[banana28]

Hi, I'm creating realistic character.
The left photo uses Displacement-Subdivision, I copied this setting from WikiHuman's Digital Emily. So I think it's popular setting.
It is fast and clear. But if my case as using UDIM, I've got seam there.
So I configured another setting using 3D mapping, however this time, it takes so much longer and produces blurry displacement.
I want to know the proper displacement setting for using UDIM.
Thanks for taking time to read.

check texture filtering make sure its either off or low value for displacement (with subdivision)

Hi, I tried it, yet couldn't see any difference.
However, I happened to notice this problem only occurs when using VraySkin Mtl.
So now I'm trying to use VrayALSurface Mtl.
