Editing Renders

After generating a render you can edit it directly without starting from scratch. The edit panel has three modes: Edit, Extend, and Paint.

Edit

Apply targeted changes to an existing render using AI.

Facade colours — Quick colour swatches let you change the building colour in one click: White, Cream, Light grey, Anthracite, Black, Terracotta, Sand, Sage. Click a swatch to add the colour instruction.

Custom instruction — Type any change you want to make: "Add a wooden deck on the ground floor", "Replace the flat roof with a green roof", "Remove the scaffolding". Combine colour swatches with a custom instruction freely.

Model — Choose which model handles the edit. GPT Image 2.5 is the default and handles most edits; Kontext Pro is a fast, low-cost option for small changes.

Extend

Expand the canvas of a render outward — the AI fills the new area to match the existing scene's style, lighting, and perspective.

1. Choose a direction using the compass picker (↑ ↓ ← → — multi-select supported)
2. Set extend amount: +25% or +50% of the current image
3. Optionally describe what to add in the new area (e.g. "mature trees and garden", "parked cars and street")
4. Click Extend render

Paint (Inpaint / Remove)

Precisely edit a specific area by painting a mask over it.

Inpaint — Paint over the area you want to change, then describe what to replace it with. Only the painted zone is edited — everything else stays identical.

Remove — Paint over an object to erase it. The AI fills the area naturally with the surrounding background — useful for removing trees, cars, scaffolding, or other unwanted elements.

Brush controls:

• Adjust brush size (10–120px) with the slider
• Toggle between Brush and Eraser to refine your mask
• Click Clear mask to start over
