Answer

Short answer:

You can use the Edit feature to modify specific areas of an image using selection tools like the brush or lasso. This allows you to change details, swap materials, or remove elements without altering the rest of the composition or generating a new image from scratch.

Overview

In architectural visualization, it is common to generate an image that is 90% perfect but requires small adjustments, perhaps the lighting is ideal, but a piece of furniture is incorrect, or a texture needs changing.

Regenerating the entire image often results in a completely different output, losing the elements you liked. Rendair AI solves this through Inpainting and Variations. These tools allow you to iterate on specific parts of a design while preserving the overall structure and mood. This approach moves the workflow from random generation to controlled refinement.

How it works

Refining an image relies on isolating the area you want to change.

1. Select the image: Open the render you want to refine in the editor.

2. Choose a selection tool: Use the Brush for organic shapes or the Lasso for precise architectural lines.

3. Highlight the area: Draw over the specific object or surface you want to change.

4. Describe the change: Enter a text prompt describing only what should appear in the selected area (e.g., "concrete flooring" or "remove person").

5. Generate: The system updates only the masked area, blending the new pixels seamlessly with the existing image.

Capabilities

Refining allows for granular control over the final output.

• Material swapping: Change a specific wall from brick to plaster or a floor from wood to tile without affecting the lighting.

• Object removal: Highlight unwanted elements like stray people, cars, or artifacts and prompt the system to remove them.

• Object insertion: Select an empty space and prompt to add elements like "potted plant" or "designer chair."

• Style variations: Use the Variations tool to generate alternative versions of the entire image that keep the same composition but explore different lighting or artistic styles.

• Detail enhancement: Use Upscale to increase resolution (up to 8K) and sharpen details once the design is finalized.

When to use this

• Client feedback: When a client approves the massing but wants to see different cladding options.

• Correction: When the AI generates a structural error or an illogical artifact in an otherwise good render.

• Staging: When you need to quickly test different furniture layouts in an empty room.

• Final polish: When preparing an image for high-resolution export and you need to clean up small noise or blurriness.

Limitations or notes

• Selection accuracy: The quality of the edit depends on how accurately you select the area. The Lasso tool is generally better for straight architectural edges.

• Context awareness: The AI blends the new element with the surrounding light and perspective. If the prompt is too different from the context (e.g., placing a skyscraper in a living room), the result may look unnatural.

• Resolution: Editing tools inherit the aspect ratio of the base image.

• Upscaling limits: Upscaling is designed to add definition, not to change the design. If you need to change geometry, use the Edit tool before upscaling.
