Hogan,

The tracker sensor should be attached to the EyeTransformMatrix if you want
head tracking for your system. Couple of questions:

1. What version of ParaView are you using?
2. Can you share your State and PVX file with me?
3. What are the units of your tracker?

We should be able to resolve the issue.

Thanks,
