Hello @james1,

Welcome to the Convai Developer Forum!

Which version of Convai Plugin are you using?

I’m using the latest from fab. https://fab.com/s/93b9dfdeaa46
However, I found the bug already, its the ConvaiBaseCharacter blueprint - ConvaiChatbot - under details panel - Sound - Volume Multiplier cannot set above 1.0. Everytime this attribute set more than 1.0 will have package error.

Hey! The build is failing due to two issues:

  1. TDxUnrealEditor plugin has a duplicate class or constructor in TDxUnrealEditor.Build.cs. Please remove the redundant definition.

  2. In the Convai plugin, make sure Convai.Build.cs contains:

public class Convai : ModuleRules

and that it’s spelled and structured correctly.

Also, try disabling the TDxUnrealEditor plugin it might be conflicting with the Convai plugin.
