These 4 environments house minigames accessed via portals from the Sanctum. In these rooms I focused on crystal and white stone as the main materials, with a lot of work going into the shader to ensure a nice refraction effect. The colours brought in from the portals help to distinguish the rooms while the shapes were largely determined by gameplay requirements. The final room is quite dark as it contains a puzzle based on lights which needed to be visually distinct from the rest of the environment.
