Home 3D for later streams are okay, but 3D debuts are special occassions. It's not something you can just do by setting up a VIVE at home and call it a day by doing a half-assed zatsudan. They made a skit for Botan's 3D, modeled an entire city, had studio guys (or KanaCoco) play the role of gunmen, most likely had several tech guys to take care of changing the scenery & adding props in the background, not to mention the camera work, adjusting audio, etc.
There's a reason why all this stuff is done in a studio environment, with a team of people.
