This is a fan-art of Minas Tirith from The Lord of the Rings. I made it within a month.
I always loved this environment from TLOR movies. Its bright colors, design, and dimensions make it such an attractive environment.
For the modeling process, I went for a modular approach. This fortress has many similar pieces that could be used to build all of its structure.
But the key for the creation of this environment was a unique Texture Set made through the sculpting of a Trimsheet in Zbrush, which I textured in Substance Painter afterward. This technique is really useful for optimization and that's why it is used a lot in game development and real-time applications. I used this unique Trimsheet for texturing 90% of the environment. A few other unique assets were then textured with their own Texture Set.
