Hi! I understand that the rendering process in Archi is running, but you're not seeing any output. Let’s try to get this sorted out together.

Could you tell me a bit more about what's happening? For example:
- Are you using any specific rendering plugins or features inside Archi?
- Have you noticed any error messages, or does it just freeze without output?
- Did this issue start suddenly, or after some changes like installation or updates?

In the meantime, here are some common steps you can try to fix this kind of issue with Archi rendering:

1. Check for Stuck Processes: Sometimes rendering gets stuck because related processes (like MAXON or Cinerender components) remain running in the background.
- Open Task Manager (Ctrl+Shift+Esc), look for any MAXON or rendering-related tasks, and end them.
- Then restart Archi and try rendering again.

2. Verify Installation Integrity: An incomplete installation of the rendering engine folders (e.g., Cinerender folder) can cause no output.
- If possible reinstall or repair Archi to ensure the rendering components are fully installed.

3. Simplify the Scene: If your model is very complex, try reducing the number of objects or layers toggled on to lessen the load on the renderer. Sometimes heavy scenes cause rendering to stall without outputs.

4. Try Different Render Settings: Adjust render quality settings to a lower preset or reduce parameters like reflections and global illumination to see if a lighter render succeeds.

5. Update GPU Drivers: Make sure your graphics drivers are fully up to date, as outdated drivers can interfere with rendering.

If you have tried any of these already or can provide more details on your setup, let me know and we can dig deeper!

Does this help so far? Are you able to check Task Manager for stuck processes or try simplifying your scene?
