Unity has a light version of FMOD baked into it, but until now, FMOD Designer had been left in the cold with Unity integration. A plugin from SquareTangle is often stumbled upon when looking for solutions to this problem but their plugin is now dated and difficult to work in tandem with Unity’s flavor of FMOD. This plugin was developed for a game called Arctic Divide and will soon be released to the Unity community through the Unity store.
Archonic’s FMOD Unity plugin works with Unity’s free version engine, works in tandem with the built in FMOD, and has been tested with versions 3.4.x and 3.5.x.
This plugin will be released once it has been polished and an example project that showcases it properly has been created. Arctic Divide is in it’s last few months and I will be working on releasing the plugin once that project has wrapped up.
