How to Edit a Render Without Starting Over

How to edit a rendering without starting over

If you've already generated an image in Redraw but need to make some adjustments, you don't have to create a new rendering from scratch.


There are two main ways to edit an existing image:

  • Use the Image Editor, especially for specific changes to selected areas, general adjustments, and filters;
  • Use the Text to Image feature with models such as Nano Banana Pro or Nano Banana 2, using the original rendering as a reference.

The best option depends on the type of change you want to make.


How to edit using the Image Editor

The Image Editor allows you to continue working directly on an image you've already generated while preserving the parts that don't need to be changed.
It includes three modes:

  • Text: applies a general change to the entire image;
  • Select Area: modifies only specific regions or objects;
  • Filters: adjusts aspects such as exposure, highlights, shadows, gamma, and brightness.


Editing a specific area

If you only need to replace a sofa, change a wall, replace a light fixture, or modify the material of a piece of furniture, use the Select Area mode.
You can choose from four selection tools:

  • Magic Selection
  • Lasso
  • Brush
  • Rectangle Selection

After selecting the area, write an instruction explaining exactly what should be changed.
For example:

  • “Replace the current sofa with a beige linen model.”
  • “Apply a light wood finish to this wall.”
  • “Replace the light fixture with a modern gold model.”
  • “Change the material of this piece of furniture to dark wood.”

Each selected area becomes an editing layer. You can create up to four layers in the same editing operation and process all the changes at once.
The parts of the image that are not selected remain preserved.


Can I use a reference image in the Editor?

Yes.
Both Text mode and layers created in Select Area mode allow you to add a reference image.
This can be helpful when you want to apply:

  • A specific furniture model;
  • A texture;
  • A color;
  • A wood pattern;
  • A fabric;
  • A material or finish;
  • A visual style.

Even when using a reference image, you should also write an instruction explaining which characteristic of the image should be applied.


How to edit using Text to Image

Another option is to use the rendering itself as a reference in the Text to Image feature.
For this type of editing, we recommend using:

  • Nano Banana Pro
  • Nano Banana 2

These models can be used when you want to send the full image to the AI and describe the desired changes through text.
The process is simple:

  • Upload the image you generated;
  • Write a prompt explaining exactly what you want to change;
  • If needed, add another reference image.

The model uses the original rendering as a base and attempts to apply the requested changes.


What can I change using Text to Image?

You can request changes such as:

  • Textures;
  • Colors;
  • Materials;
  • Objects;
  • Scene elements;
  • Decoration;
  • Details that were not interpreted correctly.

For example:

  • “Replace the wooden floor with polished concrete.”
  • “Replace the white wall with a concrete wall.”
  • “Add decorative plants next to the sofa.”
  • “Remove the light fixture in the right corner.”
  • “Change the cabinet color to matte black.”


How to use a reference image in Text to Image

In addition to the original rendering, you can upload another image as a reference.
This is useful when you want to visually show a piece of furniture, material, texture, color, or another element that should be applied to the rendering.
For example:

“Replace the bedside lamp in the first image with the lamp from the second image.”

In this case, the first image is the rendering that will be modified, while the second image serves as a reference for the element that should be applied.


What if the area is difficult to identify in Text to Image?

When using Text to Image, if the element is located in an area that is difficult to describe, such as the background of the scene or close to other objects, one alternative is to visually mark the area before uploading the image.
You can draw a line, circle, or another colored mark showing where the change should happen and explain the marking in your prompt.
This can help the model identify the area that needs to be modified more accurately.
In the Image Editor, this process is more direct because you can select the exact region you want to change using the selection tools.


Which editing method should I use?

If you need to preserve most of the rendering and modify specific objects or areas, the Image Editor is the recommended option.
It allows you to select exactly where the change should be applied and work with up to four regions in the same editing operation.
Text to Image with Nano Banana Pro or Nano Banana 2 is an alternative when you prefer to use the full image as a reference and guide the changes through a prompt.
In both cases, clear instructions and reference images can help the AI better understand the desired result.
