Blood Shot: Vein HDA
Blood Shot is a Interaccess Media Arts Prize nominated first-person shooter game made in Unity, solo-developed from scratch and inspired by Star Fox, Playstation 1 games and medical photography techniques.
Over the course of the game, the human body the player is trying to save undergoes a physical transformation, but the player can only see this through changes to their “vein map”. This HDA allows for the easy generation of different vein geometry from different humanoid 3D models.
