Hi. I am currently stuck on an error. I left an image below to help understand the issue. Basically I’m having a hard time understanding what to do when the EventRef is obsolete. I looked at other forums and tried to copy their approach but that just raises more errors. I want to add basic first person footsteps sounds that change based on the terrain.

Hi,

What version of the FMOD integration are you using?

The issue is `EventRef` was made obsolete in FMOD 2.02, I would suggest running the `Event Reference Updater` ([Unity Integration | Tools](https://fmod.com/docs/2.02/unity/tools.html#event-reference-updater)), which walks you through the process of changing references to `EventRef` to `FMODUnity.EventReference`. It can be found in the FMOD drop-down on the Unity toolbar:

Hope this helps!

Hi,

What version of the FMOD integration are you using?

Did you run the Event Reference Updater?

I’m currently working on upgrading an old project to be able to build with the newest version of FMOD (2.03+)

I’m using the Event Reference Updater to swap all EventRef to EventReference

I have 80~ scenes to parse each time I need to run the scan and it takes more than 20 min.

I would love to be able to tell de Update to **just scan opened scenes** , or scenes from the Build settings. Instead of the Updater going through all the project’s scenes (most of which i don’t need to update anyway)

Thanks 🙂
