I'm looking for solution to get rid of old version of MRTK
and start using new version of MRTK for Unity sharing applications.
but i am no sure still the new version is supporting sharing as well as annotation or marking on shared holographic objects.
i had tried to find out the solution everywhere on Google and youtube to draw circle or highlight the part of shared object. still i did not able to get the solution.
this i had achieved via line render, there is Draggable
script support provide by MRTK v2. using that and LineRenderer i was able to do it.
Thank you @julia-schwarz for such nice video posting.
