Hi!
This project is called Church on the sea.
To realize this kind of render I used a 3d model of a church I had from one of my courses that I did months ago. The model was made due to photogrammetry. The Church is located at the city of Castelgrimaldo, in Mantua, Italy.
To simulate the ocean waves I used a displace map with different orientation.
Hope you like it,
Branosh!
