Hi @Effielyons,
Thanks for the clear reproduction steps and screenshots. I can see what you mean: rather than generating the requested fire within the selected region, Firefly Image 5 is placing a small flame almost entirely at the edge of the selection.
Since this was reported on Photoshop 27.8, could you first update to the latest v27.9.1 and test the same image, selection, and prompt again?
Could you also install the latest Photoshop Beta 27.11 from Creative Cloud Desktop > Apps > Beta and repeat the exact test there?
If it still happens, could you try the same test again with a more descriptive prompt, rather than just "fire"?
For example: “small realistic flame burning, with natural lighting and soft blending into the surrounding scene”. Please keep the same selection and compare the result.
This will help us determine whether Firefly is interpreting the short prompt as an instruction to add fire near an existing boundary, or whether it is actually failing to constrain the generation to the selected area correctly.
If it still doesn’t work, please also paste your Help > System Info > Copy information here. Also, share a screenshot of the layer panel.
Let us know how it goes, and we’ll have a much more specific case to take forward.
Best,
Anshul Saini
