Hello Friends,

I’d like to implement some wave-sounds when the player comes near to the shoreline. I’m wondering if the is a better solution to implement the trigger-zone, than using multiple 3D spheres and place them along the beach.

I’m thankful for any advise  
Max

I quite like using a (muted) transceiver transmitter along with multiple transceiver receivers all along the line. It’s quite effective, no phasing issues, a unique soundscape always coming from the right direction, and it keep things quite simple. You just need to play with the sound size and the distance between the receivers.

I used the workflow alcibiade described and it worked very nice. Took me a little bit to make the receivers work the way I wanted them to work, but it was worth the effort

Also, I forgot to mention, you’ll have to limit the number of instances with the virtualisation stealing mode to save some CPU.
