Output

![Bria Generative Fill: Golden portal in the archway](https://media.comfy.org/website/workshop/bria/generative-fill/golden-portal-in-the-archway.png)

Example

## Try an example

- Fill the black opening of the archway with a radiant golden portal: swirling molten light in bands of amber and gold around a blinding white centre, drifting embers and slow sparks floating out of it, and a warm glow spilling across the mossy stone, the broken columns and the surface of the reflecting pool. Keep the masonry edges of the arch crisp so the portal sits inside the stone. Photorealistic, no text.
