Texture distortion occurs when importing a model with three million faces

[KetherGame]

UE 5.1.1
The first picture is a model with three million faces imported from the current version, it has obvious texture distortion. The second picture is the same model imported from the old version of UE that has been kept in my project with the version update.
I’m not sure whether this problem is related to the ue version. I’m using blender 3.4. I have tried both the “send to unreal” plug-in and the default export function of blender, and the result is the same.
p.s. I exported the model from unreal to blender then find this issue, I close nanite of this model before exporting it.
Any one know how to fix this?

Most likely due to UV precision:

UV Precision Bug When Importing OBJ Models

Hi , This is expected since by default static meshes will use 16bit for standard UVs to save memory. Using full precision UVs will use 32bit for more accuracy. This will happen with FBXs as well as OBJ files. The further a UV island is from the 0,1 space the more it can have issues when not using full precision UVs enabled. Looking at your test asset this is clearly visible when looking at the distance the UVs of the pieces in question are from the 0,1 space. Here is an example: UV spaced …

Not works , I think that setting is for LOD, not for nanite, but still thanks, UV should be the point
