So, how does our Blocking process go? Before starting the process in itself, I design the level on a 2D layout, defining where the puzzles, stealth zones and alternative and secret path’s will be. Once I have this, I create a scene in Unity and start to reproduce all its elements with simple shapes, based on the 2D layout and the concept art of the zone. Initially, I used cubes and simple meshes to make all the blocking but it was really cumbersome and the final result wasn’t as precise as I wanted.
