ok nope this didnt work. it worked because i tested it by putting the uv’s of the 1009 to 1001. I found this and it solved it [SOLVED] UVs from imported mesh slightly distorted causing texture misalignment - General / Feedback & Requests - Epic Developer Community Forums (unrealengine.com)
not at first because nothing happened when i click the check box. turns out there’s an apply button at the bottom of that section. so don’t just search “uv” in the search box cos the apply button wont show.
tick full precision uvs and click apply
