Hi Convai Team, I am implementing a custom vision pipeline using **SDK V4** in **Unreal Engine 5.5**. Instead of capturing the in-game 3D world, I am streaming a **Live Physical Webcam Feed** into the system so the NPC can see what I am holding in real life. I have successfully set up the rendering pipeline, but I am struggling to get the EnvironmentWebcam component to actually transmit the frames to the backend. **My Architecture:** - **Player BP:** Holds the ConvaiPlayerComponent and EnvironmentWebcam component. - **NPC BP (Dr. Layla):** Holds the ConvaiChatbotComponent. - **Pipeline:** Real Webcam ➔ Media Player ➔ Dynamic Material ➔ Drawn to RT\_convai\_vision (Texture Render Target) on Event Tick. **Current Status (What Works):** 1. **Rendering is perfect:** I can see my live webcam feed appearing on the RT\_convai\_vision texture inside the Content Browser and on in-game debug planes. 2. **Logic Linking:** Since the components are on different actors, I am using a BeginPlay script on the Player to find the NPC, get the ConvaiChatbotComponent, and assign it to the EnvironmentWebcam using **Set Chatbot**. 3. **Debug Confirmation:** My logic prints a “Success” string, confirming the Cast and Set operations passed. **The Issue:** Despite the texture updating in real-time and the Chatbot being linked, the **Vision System appears to be “sleeping.”** - The Output Log shows **ZERO** entries for LogConvai: Sending Vision Frame… - The NPC responds with “Please show me the item,” indicating she is receiving no visual data. - I have enabled Auto start Vision **Question** Is there a specific initialization order required when using a Custom Render Target with a disembodied EnvironmentWebcam? Does the component need to be “woken up” or re-initialized after I manually assign the Chatbot Component at runtime? Any help would be appreciated! ---
