Select the sky, the entourage, a facade panel or the cars in the way, describe the change, and only that area goes to the model. The rest of your render stays exactly as it left the renderer.
A patch is one selected area, one sentence, and as many variants as you want to see. The source under it never changes.
A grey sky on a competition board is a re-render away, or one selection and one sentence here.
Add people that fit the building instead of cut-outs from a library. Two or three, walking, with real shadows.
Swap the material on one elevation while every window and joint line stays where the model put it.
Remove them and let the road surface, kerb and markings continue on their own.
Drag a rectangle, draw a lasso or click a polygon around the part to change. Add a reference area if the prompt should say "like #2".
Type the edit or pick a preset. Try it as a draft for one credit, then run the keeper at full quality.
The result is pasted back with a feathered edge and adjustable opacity. Flip between variants on the canvas, or hold Space to compare with the source.
A flat PNG, a layered PSD with one layer per patch, or the whole picture enhanced and upscaled by Topaz.
Restore from Original finds where an AI-enhanced render drifted from your model and puts each area back, one patch at a time, with your rendering left as the reference.
Credits are pooled across a team. A standard edit is two credits, a draft one. See pricing for the detail.
