After I’ve done everything with the machine, I imported the scene as a reference to a new scene for importing camera and locators. In this way, I could go back to the reference scene and make any adjustment, and it will update automatically in the new scene. Then I imported the camera and locators that I exported from Nuke as OBJ files.

I locked the position of the camera in case that I touch the tracking information on camera accidentally. And then I imported the foortage as image seqence from camera. It’s important to check the box of Use Image Sequence, it’s the reason that my backgound image didn’t move at all in the beginning.

I lighted the scene, and I found that the texture of meters is black. I search on google and saw someone said that it might be the transmission in the render settings. So I checked the render settings and the transmission is 0. When I turned it up to value 2, the glass is not black anymore.
