I'm modifying the hololens academy 210 project.
I would like to tag along the whole astronaut. is that possible eventhough the astronaut is made of different parts?
I tried putting astroman as the object to tag along but it didn't work.
have you tried Parenting the adding the astronaut to and empty collider that fits his shape and using tag along on the collider?
Here's how you could add Tag Along and Billboarding, https://codeholo.com/2018/12/24/tag-along-billboarding-and-other-menu-elements-for-hololens-apps/ a lot has changed with updates to the MRTK
