I am glad to share Pier Building, i inspired by the historical pier buildings in Istanbul city. Ready to use for Unreal Engine 5. There is no texture maps for Unity, but you can export textures from .spp project.
15K Triangles
26x13x10 meters
3 UDIM Maps: There are overlapped uv parts for semi-modular meshes that you can take a look from pictures. Third part is empty. For third uv, you have to match the thirt part of UV to 4th section. It is already automatically matched when you select UDIM instead of Single Image in the shader section in Blender.
Clean topology, no n-gons, all triangles.
