I am following the documentation step by step but I keep running into this. I tried with a custom metahuman I made as well a preset metahuman and still get the following. Anyone know how to get around this?

Hello @jesseazueta,

Welcome to the Convai Developer Forum!

Could you share more details about when exactly this issue appears? Does it occur suddenly, or after a specific step during the integration process? The more context you can provide, the better we can assist you. Looking forward to helping you resolve this!

This is what I did. I created a new Unreal project version 5.4. I installed the Convai plugin and restarted the engine. I copied the API key and entered it in the project settings. I enabled the plugin and restarted the engine. I then created a new level and opened bridge. I added a preset metahuman (cooper) and enabled all the missing plugins. I then went into the metahuman blueprint and went to the body and in the details panel I went to the anim class and set it to Convai_MetaHuman_BodyAnim. I did the same with the face. I then set the parent class to Convai Base Character and I compile the BP. However the animations dont show at this stage. When I hit simulate, I get the errors above.

Thanks for the detailed explanation!

Could you please share full-screen screenshots showing exactly what modifications you made in your Metahuman blueprint?

Thanks for the detailed steps you’ve shared. Let’s try a fresh setup to eliminate any potential glitches during the initial setup:

  1. Go to Epic Games Launcher > Unreal Engine > Library, and under version 5.4, click Installed Plugins.

  1. Re-download Convai and create a new clean Unreal project.
  2. Import the Convai plugin into this new project.
  3. Start with your Metahuman: First, change its Parent Class to Convai Base Character.
  4. Then assign the appropriate Animation Blueprints (ABPs) for both body and face.

Try this step-by-step clean setup and let us know how it goes.

Looking forward to your update!
