Cinema Blend has a post up that discusses how VR was used to create the glass building that was used in the final John Wick 3 fight scene. The posted a video that breaks it down. The video is also on youtube.
…when concept illustrator Alex Nice found out he had to create concepts for a fight scene in a building made of glass, he felt that simple drawings weren’t going to be enough.
And so it was decided to design the entire structure in virtual reality. in a VR environment, cast and crew could actually step inside the building and move around inside it, getting a real feel for things like lighting and camera placements.
