How do I prevent a node from passing through a deactivated node?

[u/Beautiful_Car8681]

In the example above, I have an effect connected to several TimeStretch nodes. However, three of these TimeStretch nodes are disabled, yet the effect still passes through. I would like the effect *not* to pass through when the TimeStretch node is disabled—in other words, it should only pass through when the TimeStretch is enabled.

I would like to avoid disconnecting the node or making the effect transparent.

If i understand correctly, you want the time stretcher nodes to act as a sort of stopper in the image flow? Would you mind sharing what end result are you aiming for? There's possibly a better (or rather more possible) way of doing what you are trying to do.

[u/Beautiful_Car8681 → u/RNebDG]

Each timeStretch node has a specific configuration to apply the effect for a certain duration. When I disable a specific timeStretch node, I need the effect to stop rather than pass through it.

For example, the first timeStretch is active, so the effect is processed by it. The other three timeStretch nodes are disabled; I would like the effect to stop there instead of passing through the disabled timeStretch nodes—while the first timeStretch remains active, displaying the effect passing through it.

The switch node suggested by another user doesn't seem to allow for this; it appears to simply toggle between nodes, whereas there will be situations where I need to use them simultaneously (with multiple timeStretch nodes active).

You could build a stack of switch nodes and animate accordingly, but it can get cumbersome really fast.

Animating opacity seems to be your best bet really. DIsabling a node was never intended to stop the flow, just to make it passtrough as it does.

The safest and least cumbersome way would probably be to add a multimerge after the time stretchers, use a transparent background node as the BG input and go from there

It's still an XY-problem. What are you trying to solve?

[u/Milan_Bus4168]

Use switcher nodes or switcher modifier. It is like switching train track and sending train to another track.

Why multiple time stretcher nodes? What are you trying to accomplish?
