Hello,
We are building a mulyiplayer game using a listen-server for Steam and are currently trying to setup Proximity chat with VOIPTalker alongside SteamAudio.
We have successfully setup basic Occlusion using SteamAudio on an AudioComponent on our player for footsteps but are having trouble (game crashes with fatal error) getting this same occlusion to work with the VOIPTalker component.
Steps to Reproduce:
- On the Attenuation settings for the VOIPTalker add a
Steam Audio Occlusion Settingsobject to theAttuenuation (Occlusion) -> Occlusion Plugin Settingsarray. - Push Game to Steam
- Run Server
- Join As Client
- Push to Talk on Client (which will execute the
ToggleSpeaking 1command)
Game will crash as either the server or the client with a popup Fatal Error
We were able to get basic prox chat working by skipping step 1 in the repro steps above. So I’m pretty sure this is an issue with the VOIPTalker not knowing about SteamAudio.
I have attached screenshots of our blueprint setup for setting up VOIPTalker along side the crash log.
If anyone knows what is going wrong or has gotten this working in the past we would really appreciate any insights.
Thanks.
