I tried to create a scene with reference to a photo I found while browsing pinterest. first I created the textures. then I tried to make the walls as modular. walls, windows and frames are separate mesh. I made 4 types of windows and frames. i used a trim sheet for their textures, including the doors. I made 3 types of curbs and they share the same texture, I scultped the details with zbrush and then bake their normal textures. all pipes share the same texture file. gas and electricity boxes have uniq texture. for the windows I made a simple glass material. i put a fake curtain behind them. i simulated 2 types of curtains with blender and bake their normal textures, i made curtains from a single polygon. for the edge mesh decal Leonardo Lezzi's https://www.artstation.com/marketplace/p/dBoVb/normal-edge-decal-tutorial-hq-pdf-unity-shader?utm_source=artstation&utm_medium=referral&utm_campaign=homepage&utm_term=marketplace tutorial helped alot. i created a foliage atlas with zbrush and bake the normal information and made all the foliage materials with it. i hope you like it, i tried to convey all the details.

Leonardo Lezzi's edge mesh decal pdf helped a lot. https://www.artstation.com/artwork/l3wwa
