Perfect Nodal Offset for Virtual Production using RETracker Bliss. No More Sliding Feet!

Sliding feet and misalignment are a common problem for Virtual Production. RETracker Bliss can measure your lens nodal point and tracking offset to fix this for you. This works similar to the VIVE method I've shown before, but now you can do it with RETracker Bliss and an Apriltag. Variations of this method can be used on any tracking system that can track another object in the scene besides the camera. This tutorial shows how. It starts assuming you have already calibrated your lens distortion, if you haven't done this please check out my earlier tutorials below. If you need more info on how to use this method with other trackers, please leave a comment and I'll try to help.
