Overlay Not Showing

If your overlay isn't appearing in OBS, work through these checks in order.

1. Verify the URL Format

Your overlay URL must follow this exact format:

https://4throck.cloud/widgets/compositor/overlay?key=YOUR_KEY

Copy it fresh from the Compositor page using the Copy Overlay URL button — don't type it manually. Check that there are no extra spaces, a missing ?key=, or a truncated key.

2. Check OBS Browser Source Dimensions

The browser source must be set to 1920 × 1080. Smaller dimensions will clip or scale the overlay incorrectly.

In OBS:

1. Right-click the browser source → Properties.
2. Set Width: 1920, Height: 1080.
3. Click OK.

3. Enable Interaction

In the browser source properties, make sure Interact is enabled if you need to click through the overlay in OBS (for testing). This doesn't affect rendering, but some OBS versions behave differently with it off.

4. Check That Widgets Are Added in the Compositor

An empty Compositor canvas (no widgets added) results in a blank overlay. Make sure you've added at least one widget in the Compositor and positioned it on the canvas.

5. Clear the OBS Browser Cache

OBS caches browser source content. A stale cache can show an old version or a blank page.

In OBS:

1. Right-click the browser source → Properties.
2. Click Refresh cache of current page.
3. Click OK.

Alternatively: Right-click the source → Interact → press Ctrl+Shift+R inside the interact window.

6. Check Your Internet Connection

The overlay loads content from 4throck.cloud. If your stream PC loses internet or can't reach the server, the overlay will be blank. Check that you can open the overlay URL in a regular browser.

7. Try Reloading the Browser Source

Right-click the browser source in OBS → Refresh. This forces a fresh load.

8. Check for Console Errors

In OBS, right-click the browser source → Interact → press F12 to open developer tools. Check the Console tab for errors. Common issues:

• 401 Unauthorized — your overlay key is wrong or revoked. Get a fresh URL from the Compositor.
• Failed to load resource — network issue or server down. Check status.
