[Feature Request/Question] Extending uniformly-lit stage for environment lighting without central objects

[sashaok123]

Description

Thank you for creating LuminaBrush! I'm particularly interested in the uniformly-lit stage application showcased in your framework:

Specifically, I'm intrigued by this application mentioned in the README:

One obvious side-product of this method is an application to use the "uniformly-lit stage" independently to somewhat "delight" images

Question

Is it possible to extend the uniformly-lit stage technology to modify lighting in scenes without central objects?

I wonder if this technology could be integrated with rgbx and rgbx in ComfyUI for broader scene relighting:

Technical Details

Currently, your framework shows excellent results with the two-stage approach:

1. Converting images to "uniformly-lit" appearances
2. Generating illumination effects with user scribbles

Questions:

1. Has the uniformly-lit stage been tested on scenes without prominent central objects?
2. Would integration with rgbx be technically feasible for expanding lighting manipulation capabilities?
3. Could the current model architecture handle broader environmental lighting changes?

Potential Use Cases

• Interior architectural visualization
• Landscape photography lighting adjustment
• Environmental design lighting studies
• Scene atmosphere modification

Would love to see this extended to environmental lighting!
