### What do you need help with? Question ### Installation method Unity Asset Store ### Issue area Other ### Impact Major - a core flow is broken ### Unity version Unity 6.3 LTS (6000.3.23f1) ### Convai Unity SDK version 4.6.0 ### Target platform Unity Editor ### Where does it happen? Custom scene ### Short summary Actions layer weight stays on 0%, no errors given. ### What happened? I have been working on a project using Convai. I’m currently trying to make the AI decide what kind of animations it should play during a conversation with the player. However, I have noticed that the layer weight of the Actions layer stays at 0%, even when succesfully running the command/animation. This causes the animation to not play visibly. I get no error messages, nothing wrong in the Troubleshooter and I have been trying to debug this problem for days. Does anyone know what is wrong here? I had the same problem with the talking layer, but I fixed that by upping the expressiveness of the AI (which was first low). The problem isn’t the mask or the model the animation is made for. Other animations also don’t work when I make a custom gesture. I am using the 4.6.0 convai SDK for Unity (among NPC AI Engine 4.6.0). This is on Unity 6.3 LTS. ### What did you expect? I expect the actions weight to be higher than 0%, so that the animation works and is visible to the player. ### Steps to reproduce 1. Create a ‘Play the Gesture’ action with any animation. 2. Put the animation in your animation set. 3. Press play in the Unity Editor, request the gesture, and, well, see it not working. ### Screenshots, recording, logs, or minimal repro ![Pasted Graphic 1.png](https://canada1.discourse-cdn.com/flex004/uploads/convai/original/2X/3/39a869821105fd4e749567ce8491caf13a04b092.jpeg) ![Pasted Graphic.png](https://canada1.discourse-cdn.com/flex004/uploads/convai/original/2X/6/6f9e7135d4dda4ee7e28f3d6cd5a41a0a4262ce8.jpeg) ### I checked the relevant documentation, resources, and similar forum posts before posting. on ### I confirm that I did not include API keys, tokens, passwords, secrets, private character data, private conversation logs, or customer data. on ---

Could you please share the unity logs? ---

How do I do that again? Sorry, I normally don’t work in Unity. ---

What exactly are you trying to do? If you’d like, you can also do it quite easily using Codex or Claude Code. Our Convai Unity SDK supports MCP. ---

I have made gestures that I want the AI to execute. I want it to be able to play those gestures when it is logical to do so in the conversation (so without player input), but the actions animation layer stays on 0% and doesn’t move, even when linking everything together with no errors. However, if you’re talking about sending logs with Codex, correct me if I’m wrong, but isn’t Codex a paid feature? I currently do not have a paid subscription on Claude. Reason I’m asking is that, the logs you need, is that my console output? I’m guessing I am not supposed to just copy paste every line there is, right? If not, what am I supposed to do and how? ---

1. Watch the gesture live. Enter Play Mode, select your character, and open the Body Animation window (the button on the Convai Body Animation component). Go to the Live tab. Ask for the gesture and look at the Action row: does it show your clip’s name, or (none)? The transition log at the bottom should then show a line like Playing:. If it never does, the gesture is not starting, rather than playing invisibly. 2. Check the gesture name. The Play Gesture behavior needs to know which gesture to play. It uses, in order: the action’s gesture parameter, the behavior’s Default Gesture field, and finally the action’s own name. If your action is named “Play the Gesture” and has neither of the first two, it looks for a gesture literally called “Play the Gesture” and quietly gives up. Either set Default Gesture to the exact name in your Animation Set, or rename the action to the gesture’s name (for example “Wave”). In the Console, look for a yellow warning containing no matching action in set. That message confirms this is the cause. 3. Check the strength sliders. In your Body Animation config, make sure Action Strength is above 0. In the Animation Set, make sure your gesture’s Target Weight is above 0. If it still doesn’t work, please send: a screenshot of the Live tab while you request the gesture, a screenshot of your action’s Inspector, and only the yellow or red lines from the Console. To copy a line, click it and press Ctrl+C. If you’d prefer the full log, it’s at %LOCALAPPDATA%\Unity\Editor\Editor.log, or use the Console’s ⋮ menu and choose Open Editor Log. For the AI choosing gestures on its own: once the gesture plays when you ask for it, write the action’s description to say when it should be used (for example “when greeting or saying goodbye”). The character decides from that description. ---

I have found the solution. I tried adding animations through Convai \> Body Animation Editor and then the content tab. This apparently didn’t work, so I had to manually add the animation directly in the animation set itself. No clue why it didn’t work via the content tab, perhaps I forgot to create an animation set. ---
