Lookup failed for InputBusModel

FMOD Studio

Hello, after receiving some warnings such as ‘AsyncCommandBuffer::growBuffer’ and ‘SoundSourceInstrumentInstance::startChannelIfReady : Loading delay exceeded, sound may play at incorrect time’, I ran the profiler and got the following warnings/errors for several events, all of which had GUIDs associated with snapshots. Any idea on what might be going on? I wasn’t able to find any documentation on what the InputBusModel is. Thank you!

Make sure you are constantly calling update, otherwise the command buffer can fill up and need to resize, otherwise the buffer size can be set via FMOD_STUDIO_ADVANCEDSETTINGS::commandqueuesize.

Hi Cameron, thank you so much for your reply. Could you elaborate on what exactly needs to be called in update? I had assumed that RuntimeManager handled this sort of low-level activity - are you referring to the calling of events / setting of parameters in update?

Best,
Maximilian

Are you referring to the RuntimeManager in the Unity Integration?

Are you able to share your entire output log?
What version of FMOD are you using?
