Is there a way to have a bi-directional link/expression between two different nodes, even a single channel, and not use Mimic link. For instance, lets say I have a Matchbox in the top level of Batch, but also the same Matchbox within an Action. I want a change in a particular field in either, to be reflected in each. So if I set value X=1 in node A, it changes in B. Or if I set value X=2 in B it is reflected in A.
Mimic link won’t work between these nodes since they are essential in different logical spaces.
You’re restricting your approach to two channels.
build the matchboxa s if you were building a HUD in any sensible piece of 3d software.
build a controller, and have subordinate nodes accept the channel changes of the controller node.
Context views means this is trivial.
not if I want to be able to control something at multiple levels.
I suppose I could have multi-viewport up with top-level Batch up where the “controller” is, and then second view with whatever I’m working on. But I don’t work that way.
