Bunker fbx concrete building in desert 3D model

This model is actually an example. Every professional 3D software can read the fbx format (I need therefore only one app). The first picture shows it in the TNGViewer. In the second we see the uvmesh. The normals are adjusted for Unity etc., the model otherwise broken if that's wrong uvmesch. Then a few images from Unity and Cinema. In the ZIP file, the main textures are baked (for practice). You can simple drag the textures to your favorite app. (But the model includes an integrated simple texture.)
