I modelled these in Blender and textured in Substance 3D Painter. For the stairs, I created one step and arrayed it a few times. The bannisters added a curve and adjusted it to go along with the staircase. I then duplicated them a couple of times. The ladder and cage were just simple models anyone can achieve that knows Blender. The textures were fairly simple. In Substance Painter. I added a metal material and gave it some dirt and edge ware. I hope you give me a like and maybe purchase it.
