Thank you Roberto for the kind response. I actually use Attachment Controller some other receptor objects floating on the surface of the cell membrane. Funny how the human mind is blind to things when looking from another perspective:
I don't have any animation regarding the granules so I always thought of them as a single object. Also the number of the granules were high so I created them with pflow and snapshot, so they were a single mesh with spherical elements. I notice just now that it was obvious from my last sentence, that each granule has to be a separate object to have a separate center. How dumb of me. 😂
A sub-object method may still be appreciated although seems -to me now- less likely to be possible.
Let me ask a follow up question :
The two T shaped elements are what I used the attachment controller (constraint) for. Actually they are linked to the receptor objects below them and the receptors are constrained by Attachment Controllers.
Now there is a third object- a pollen- moving between them and connecting the two.
In this case I need the attachment to cell surface to move on with the noise deformation, but also the close ends of the T shaped objects also connected to the "o" shaped pollen.
I could only think of using a link controller to link the pollen to one of the T's at the appropriate frame Then also use it as a Linked Xform Controller object for the other T shaped object.
One of T shaped objects will be deformed and that is not what I prefer, but I ll have to use it if I can't find another method. I am also trying a look at constraint but the shapes are not regular and I can't keep it looking at the correct direction.
Do you have any recommendations for this task? (I might again be asking questions with obvious answers. The objects have to be either deformed or somehow get unlinked in terms of rotation. I am looking for a method to achieve the latter.)
