Why does the "set volume multiplier" seem to have no effect during gameplay?

[uced]

Hello,

I am trying to use the “set volume multiplier” node to change some music volume during gameplay.

It works well when put in the construction graph, so i know the setup of the node (target etc.) is correct.

But when triggered by an event in gameplay it seems to have no effect. When i debug the blueprint, the flowing line goes through the node and all the other actions on the event line are triggered correctly. But this particular node seems to do nothing.

Any idea to make the “set volume multiplier” work during gameplay ?

Thanks

Cedric

Maybe that will simplify my question.

How come this is working

And not this ?

edit: the images won’t show, so to be clear: the “stop” node works, the “set volume multiplier” doesn’t, everything else being the same.

Thanks

Cedric

You’ve no doubt solved this by now but I’ll reply anyway since others may come across the same question.
This volume multiplier will only be applied when the playsound object is triggered to play, so not useful for music (unless you have a short repeating phrase). To change the volume of a sound whilst it is playing you need to use a continuous modulator node within the soundcue and then set float parameter.
