I am a newbie, so sorry for the silly question. Since I was little I wanted to create a 3D environment of my little city. I used to work with the Unreal Tournament Engine when I was 10 and started with my house.
Now I work with drones and they help me create 3D models from pictures I take around monuments. You can see an example here: https://skfb.ly/6IvKI
I was able to import this model into the Unreal Engine. The quality is quite good, but as you can see, once you get closer to the tower (you maybe have to wait a little bit before it shows the best quality) the windows are not very good. Also the door and the stairs are not in a good shape.
Before importing this kind of model, can I improve it somehow? Which software can I use?
Can I change the door and the windows with something from the Engine?
Which workflow do you suggest?
Sorry for the silly questions, I hope you can help me. It would be good to work with 3D models generated with softwares like Agisoft Metascan.
