Hi,

If I use a parameter such as “Audio DyanmicScale” or “FMOD Scale” etc,  
can I make an automation controlling Min & Max Distance of 3D Panner?  
I just figure out I can make an automation controlling Sound Size, Min Extent and Pan overide mix.  
I think, Min distance and Max distance’s Automation will be more useful than Sound Size, Min extent or pan overide mix, if possible it is.

I would love to know how to do this as well. It’d be so cool to be able to automate min/max distance as a param.

Thanks for your question. You cannot currently automate min & max distance of the 3D panner (this item is on our backlog). However, you can set these values programmatically using Studio::EventInstance::setProperty() with FMOD\_STUDIO\_EVENT\_PROPERTY\_MINIMUM\_DISTANCE and FMOD\_STUDIO\_EVENT\_PROPERTY\_MAXIMUM\_DISTANCE to set the min and max distance respectively.

See [https://www.fmod.org/documentation/#content/generated/FMOD\_Studio\_EventInstance\_SetProperty.html](https://www.fmod.org/documentation/#content/generated/FMOD_Studio_EventInstance_SetProperty.html) for more information.
