I have successfully imported 3D subsymbols into the main stage and accessed and play their timelines as per your documentation. I cant, however, seem to do the same thing when I create a subsymbol (non 3D) with a series of scales for example. When I drag the subsymbol into the main hierarchy and create a new controller and timeline for that subsymbol I cannot see the animation’s key frame option…I am not sure what I am doing wrong. For example, when i look at the solar system example provided by zappar, I can see that within the look for subsymbol there are two timelines and when they are added to the main stage these can be accessed and keyframed under the references tab of the properties tab. When I try to replicate, I cannot get the same result. Any guidance would be fantastic!
