relative references dont update?

[penpen]

Hi

i am trying to feed the parameters of metaballs into a subnetwork with relative channel references, however i notice that if i go

back up into my network and then scale etc the metaballs, that the reference to those paramaters doesnt update!?

so for example, ive made a very simple version of the problem here with a control curve and a torus,

the curve is animated, and the torus should be following it (its transforms are being controlled by a relative reference to it) however its

not until you go into the network and then try to move the curve again (ie from inside the network) that it updates..

can anyone shed some light ?

many thanks!

You're animating or referencing the wrong context? Can you post a file?

oops, meant to post it originally

Ah, yes, that looks like expected behavior. Once you merge it into the the other geometry you animate points, not object transforms. It's effectively becoming a deformation.

It depends a bit what you want to do.　In this case you could just use a point position of any point of the curve, or reference the original transform.

im trying to get the torus to follow the curve-

if you open the transform after the torus, the torus should

snap into the same place as the curve (update problems)

im simply trying to make the torus move where the curve does..

im trying to get it to update all the time, rather than when you

just open the toruses transform node

how do you bring in the original transforms ?

i put down an 'object merge' and in the 'tranform into' field i entered .

is there another way?

thanks for the help!

How about this?

You're right though, your original setup should work. It should update but doesn't.

centroid() updates properly. You could use that as well.
