I’m off the deep end here. It was just a wild guess. I have no idea about what you’re exactly doing in your model and how the images you posted above are related to your model. but personally am an avid hobby photographer and saw the slight tilt in one of the examples. If that’s related to the asymmetric yaw graphs I can’t tell. Wish you success in this project as well as the sherpa map - am already a fan. thanks for the thorough reply! Always happy to learn more.
