For the material approach of the tech, a Master Shader has been used for most of the object you will see in the game, using common techniques like world align, Uv projection or various roughness options… The project being indoor, some materials have been prioritized like sandstones, marble or concrete, which are the most used. For our characters, creatures, crystals, amber and more to react to lights, materials using SSS have been developed and polished. With Fps going from 75 to 120, the optimization has been the center of our priorities.

For the visual scripting aspect of the tech, a mix of blueprints and Behaviour trees has been used in order to have AI that would work easily for the need of the project and bring life to the environment. With hostile units being more complex, they use a Behaviour tree in order to switch states when looking for the player, and more simple AI Like Lily that switch from a waypoint system to then simply following the player, and the automated vacuum that make their own path when colliding their surrounding. Trigger boxes are used throughout the whole game to allow a smooth running of the gameplay and voice lines.
