Texture won't apply correctly to some imported .obj models

[Mercury]

Hello, for some reason I am incapable of properly applying this texture to this couch pillow, for some context, the same texture is applied to the floor and it works fine.

I just can't comprehend why it won't match what it is shown in the preview window.

Have a look in Blender to check Normals (face orientation) and UVs are correct

In addition of what Martini said, you can check if your model has a mesh problem as I can see it's a bit weird even in the viewport.

Your cushion model also has a strange triangular look in the viewport there. Also check duplicate vertices. You can use merge by distance to remove doubles.

It could possibly have broken custom split normals? If none of the other methods described here solve the issue yet, try selecting that object and see if Clear Custom Split Normals Data is an option (in Object properties panel > Geometry Data).

I'm just a noob but you were right, I went to check and for some reason in this case I had to click "add uv map" in the 2d mapping square. You guys are the quite the detectives on this.

Thank you
