These two models were created in unreal engine using simple additive and subratctive geometry to make the wall and the door frame. I have used the default textures on these models because at this point my textures weren’t ready so I could have applied them on to them.

unfortunately due to some technical issues with my pc at college I have lost few of my screen shots that demonstrated how I had created these two models, but I am sure I will able to show it in the near future with other projects and game making.
