At the moment the integration cannot visualize this (without editing the plugins source code), although it should not be too difficult to get it to work.
I will add a task to implement this in a future release.
If you are interested in editing the integration yourself, I would take a look at the DrawVisualization function in FMODAudioComponentVisualizer.cpp.
Check to see if there is a distance parameter and draw that one instead.
The min and max distances are currently used for visualizing the sounds attenuation. I have bumped up the priority of the task to add the distance parameter to this.
I’m not understanding what you mean by the value of all Spatializers.
My event has Spatializer on the master track and yet anytime the Get Property Max Distance is used, it always returns 0.0
Perhaps it’s not working as intended?
