House_Ruin_1I01_V3 has multiple, texture-related issues:
1) Texture stretching on LOD1 due to improper UV island layout. The texture stretching is difficult to see due to base-game model's white plaster texture being so uniform, but numerous instances of the issue are clearly visible if the mesh is retextured, such as with brick. Please see attached video of transition btw/ LOD0 and LOD1.

2) Improperly rotated UV island causes inconsistent texture alignment / tilting. In the attached image of the building's side, you can see that the mesh's UV island is set up such that the texture is not rotated. However, just bellow the hole in in the wall on the part of the mesh that juts out to support the roof, you can see that the UV island was rotated such that the texture has a 45° rotation.
