Render Notifications

Stay in the loop while your scene renders.

Get updates when your Blender render starts, finishes or is cancelled — right to your desktop, Discord, or even your your custom apps or third-party services that support webhooks (e.g. Home Assistant for mobile notifications).

Whether you’re rendering stills or long animations, this add-on gives you peace of mind without constantly checking Blender.

Features

• Desktop notifications with optional custom .wav sounds
• Discord Webhook integration
  • Sends a message to Discord when the render starts, and edits it as rendering progresses.
    • When the render finishes or get cancelled, a second message is sent.
  • Supports preview images:
    • For single-frame renders: shows the final image
    • First and last frame previews for animation jobs
• Custom Webhook support
  • Perfect for tools like Home Assistant, IFTTT, or your own scripts
  • Sends structured JSON payloads full of stats about your render progress.
