Hi Aximmetry staff,

I am having an issue with after turning ON “Use billboard”

Prerequisite: I am still having trouble calibrate the lens with the green screen. But the “Use billboard” seems to make a different situation, not just moving off away from the the marker grids.

Below: When the track camera tilted upwards, the whole scene is being tilted in a relative Y axis centered with the billboard instead of the world scene transformation

The chair is the testing object that is captured in the camera (In red marquee: in the center)

Below: This is the actual scene without turning ON “use billboard”

The whole scene is normal. When the track camera tilted upwards, the whole scene is being tilted in a relative Y axis centered with the billboard instead of the world scene transformation

Does the “Use Billboard” option change the perspective/lens profile? Or is there any setting that I got it wrong so the track camera already capture from a different point?
