Error message

When I am manually tracking and adjusting the Surface planar tool… I am getting a error “Unable to get surface position in front of camera” and when I click okay it pops back up and prevents me from working in mocha, I cant even close the program without force closing in in the task manager. Any insight on what is causing this or how it can be prevented/solved would be greatly appreciated.


Mocha 3.2.1

Windows 7

Yes, mocha can’t tolerate the planar surface moving behind the camera.

If you are using perspective when you track, it may be that your surface is going behind the camera in mocha and corrupting the data. In mocha, problem splines can occur when the tracking data has become so skewed it goes off or “behind” camera, the keyframes the tracking data generates can throw the shape information out of order. You may need to re-track the shape using only translation, scale, rotation, and shear instead of perspective. This is especially true for complex roto of an object that is turning away from screen or tracking an object that is turning.

Okay that makes sense good to know! thank you
