In this Model, I have used 4K PBR Textures to maintain its quality and keep it low-poly.Every window can slide up as you can see in the images. The model is made in Blender 3.1.2 and rendered in Cycles. I have included the Studio file, so you just need to open it in Blender and click on render and you will get the same result as my images. I can provide a little favor to you regarding joints or separation, just contact me.
Note: Entire model does not support Subdivision Surface/Meshsmooth.
