Fantastic '90s puzzle adventure game The 7th Guest is being remade in VR, and developers Vertigo Studios and Exkee are using a cool solution to recreate the original's FMV acting in realtime 3D environments.
In The 7th Guest, you're trapped in a toy maker's spooky mansion with the apparitions of six previous guests who mysteriously disappeared. In between solving riddles and geometry puzzles, the story of those guests plays out in the style of a dinner theater production, with semi-transparent video of actors overlaid on pre-rendered 3D sets.
