A short walkthrough of the bridge: viewport screenshots, 3D model and splat export, and using Runchat to enhance Blender renders into production-quality video.

​
How It Works

The webview runs the full Runchat web app and communicates with Blender through a local bridge. Bridge capabilities:
  • Viewport capture: Send your current 3D viewport as input to AI workflows.
  • 3D model import: Generated GLB, OBJ, and FBX models import directly into your scene.
  • Image import: Generated images load into Blender’s Image Editor.
  • Video import: Videos auto-import to the Video Sequencer.
  • Script execution: Workflows can run Python scripts in Blender.

​
Updates

The plugin checks for updates automatically when Blender starts. If a newer version is available, you’ll see a banner at the top of the Runchat panel with a download link.

​
Troubleshooting

Press N in the 3D Viewport to toggle the sidebar. Look for the Runchat tab. If it’s not there, check that the addon is enabled in Edit → Preferences → Add-ons.
Ensure Blender has internet access enabled (Edit → Preferences → System → Network). The webview requires an internet connection to load the Runchat dashboard.
Re-download and re-install the plugin. The zip includes all required Python dependencies.
Close and reopen the Runchat webview. Check Blender’s system console (Window → Toggle System Console) for error messages.
