Bad Jagged UV's with UDIM workflow on Import UE5

Hello! noob here)
I am trying to import a custom car model from 3ds max, with textures made in substance painter. model has 8 UVW sets (UDIMS) (for preview i use only body with no tires)


After export as fbx and import into UE5 i do enable virtual texture support
And some parts of my model looks very jagged like my UV’s are skewed in a very bad way

but some part are still fine, no matter where thier UV coordinated are.
i tried different export/import options but nothing seem to work, jagged lines sometimes changes their location but they still exist all over the model. reseting normals inside 3ds max didnt help either

Only when i take my cabrio roof - detach it - and make fresh UV’s, the problem is gone



but i need UDIMS for the hq workflow
Please can someone suggest some options to workaround or eleminate this problem?

PS: car model by WireWheelsClub

You can check “Full precision UV” in Static mesh properties. That’ll solve the problem.
