How to shoot mixed reality movies through HTC Vive

What do I need to prepare if I use HTC vive green screen as MR?

Hardware part:

1. Studio: the wall and floor are covered with green cloth, 5m*5m.

2. Camera: Two Solutions

A) Low cost: it is a webcam, such as Logitech webcam C930e.

B) High cost: professional camera+video capture card. For example, Sony A7S II.

3. High-performance host: Because you need to run Vive games and videos at the same time, the configuration requirements are high. The graphics card is recommended to be 980ti, and the CPU is recommended to be above i7-4790.

4. The third handle: At present, Vive can only connect two wireless handles, so it needs a longer USB cable to connect the third handle.

5.4K screen: In order to synthesize 1080p video, the screen needs to be able to accommodate multiple 1080p windows.

Software part:

1.Unity3D+SteamVR: At present, only the programs made by Unity3D support MR mode. As long as the version of SteamVR used in the game is 1.0.8 or above, it can be used for shooting. Otherwise, developers need to upgrade SteamVR before releasing the version.

2.OBS or other video synthesis software.

How to shoot:

1. Open MR mode of the game.

2. Install the camera and the third handle

3. Adjust the video synthesis software
