Is it possible to work on several animation nodes NodeTrees and to switch between them / select the active one ?

I see AN generates a "Animation Nodes Object Container" object. Is the nodetree attached to it ? And how ?

Thanks for your lights.

Animation Nodes Object Container

The Animation Nodes Object Container is created as a helper object for the Object Instancer node, in other words, it is only created when the Object Instancer node is used. Notice that it doesn't get removed when the Object Instancer node is removed and it is a single object even if you have multiple Object Instancer nodes.

Node Trees

If multiple Node Trees are presents, all of them executes based on the defined Auto Execution settings. So if both have Always option enabled, both will execute simultaneously. So there really isn't an "Active Node Tree". Subprograms are shared across Node Trees, so you can call a subprogram defined in one node tree in another.

Animation Nodes provide a fast way to disable/enable Auto Execution for the available node trees, this is done through the Overview Panel:

  • $\begingroup$ Thanks for those informations. And then, is it possible to have multiple node trees and to execulte only one of them (in a simple way) ? Thanks $\endgroup$ – gordie Apr 25 '18 at 8:55
  • $\begingroup$ @gordie Sure, just disable Auto Execution on the ones you don't want to execute. A fast and simple way to do this is by using the Overview panel in the T menu, you will see a dot beside each node tree, pressing that disable/enable Auto execution. $\endgroup$ – Omar Ahmad Apr 25 '18 at 17:37
  • $\begingroup$ Ok Omar, I didn't get that ! If you edit your answer to add this, I'll validate it. Thanks ! $\endgroup$ – gordie Apr 26 '18 at 7:39
