Mesh is distorted on Oculus Quest 2

Unity Engine

Hello,
I’ve made a reconstruction of a room from photos with RealityCapture.
I’ve imported this sigle mesh as .fbx, with all its materials (and textures).
I’m using “Unlit/Texture” materials for the reconstructed model, just to see the textures.

The Unity scene look perfectly in Unity Editor, and in a stand alone build.
BUT, when I move to Oculus Quest 2, everything is a little distotrted (for example, a straight line texture become a waved line).
I’m using ASTC 4x4 texture compression, so I think it should not be a matter of texture compression.
For sure the 3d model is quite huge (1.3ML triangles), and have a lot of “sub materials” (so, sub meshes, each one with its own unwrap).
Maybe is it a matter of geometry?

Any help would be much appreciated!

I’ll try to explain better my issue, please see this screenshot from Editor (or PC build, is the same)

Now please see this screenshot from Oculus Quest 2…

As you will see all the textures are distorted…

Here another comparison:

This problem unfornutately is much visible with Oculus Quest…

Any help?

Do you have mesh compression on high?

To be honest without knowing what the wireframes are it is hard to tell. But it looks like texture compression to be. I don’t know for sure as I’d need to see wires.

Many thanks hippocoder for your reply.
I don’t have any mesh compression on my imported fbx, please see the settings:
(P.S. I’ve also tried with “Oprimize mesh: Nothing”, but does not change)

This is the wireframe:

I’m pretty sure that’s a geometry issue, because another .fbx does not give me this kind of problem

Many thanks!
