Summary

Niagara Initialize Audio Player Dependency for Audio Player 4.0 is Disallowed
When updating from 3.0 to 4.0 on Audio Player within a niagara system it comes back as disallowed when trying to upload the project

Steps to Reproduce

Add Audio Player 4.0 with the new required dependency to an emitter within a Niagara system and then try to start the session.

Expected Result

It would work

Observed Result

Returns Disallowed object type /Niagara/Modules/Audio/InitializeAudioPlayer.InitializeAudioPlayer

Platform(s)

PC UEFN

2

The status of UCB-1035 incident has been moved from ‘Awaiting Validation’ to ‘Needs Triage’.

3

Temporary work around is to copy and paste the below (the previous version of the Play Audio script) into the emitter Particle Spawn property.

Hey thanks for the reply.
You can actually just change it back to the previous version from the button on the top right (the yellows squigglies remix sign)
