Practical Guide to Using the "Improve Render V4" Feature on Redraw

In this guide, you will learn how to use the Improve Render V4 feature, designed to enhance existing images with better quality, visual direction, and more predictable results.
This feature is ideal for anyone looking to quickly and easily elevate the realism, finishing quality, and presentation of project images.

1. Access the Platform

Log in to your account at: https://br.arch.redraw.pro/member
If you don't have an account yet, sign up at: https://www.redraw.pro/#pricing

2. Access the "Improve Render" Feature

In the main menu, select the Improve Render option.
Make sure you are using the V4 model, which brings significant improvements in image interpretation and control over the final result.

3. Upload Your Image

Click Upload File and send the image you want to enhance.
The image can be:

• an already generated render
• a concept image
• a project base

4. Choose the Improvement Type

One of the main evolutions of V4 is the ability to select targeted improvements, without relying solely on prompts.
In the new interface, each option displays visual indicators for Fidelity and Creativity, showing in advance how that improvement behaves — whether it tends to preserve more of the original image's characteristics or apply more creative AI intervention. This helps you make a clearer choice before starting the generation.

You can choose from:

Refinement

Brings more elegance and visual balance to the image, adjusting composition and finishing. Recommended for improving overall quality while preserving the main structure.
Indicators: Fidelity ↑ · Creativity ↑

Fidelity

Improves image quality while maintaining as many characteristics of the original render as possible.
Indicators: Fidelity ↑ · Creativity ↑

Realism

Brings the image closer to a photograph, with more natural adjustments to light, materials, and depth.
Indicators: Fidelity ↑ · Creativity ↑↑

Premium

Applies a more sophisticated and polished look, ideal for presentations and commercial materials.
Indicators: Fidelity ↓· Creativity↑↑

Lighting

Adjusts the scene's lighting to make it more balanced, pleasant, and coherent.
Indicators: Fidelity ↑ · Creativity↑

Understanding the Fidelity and Creativity Indicators

Each improvement option displays two indicators that show the expected behavior of that selection:

• Fidelity → how much the improvement preserves the characteristics of the uploaded image
• Creativity → how much the improvement applies changes, refinements, and visual interpretations by the AI

Each option already has its own fixed configuration.

5. (Optional) Use a Prompt

You can also add a prompt to better guide the result.

Example uses:

• lighting style
• desired materials
• scene atmosphere
• aesthetic direction

V4 has improved prompt interpretation, translating your instructions with greater precision.

Key Improvements in V4

• Better interpretation of architectural scenes
• Greater fidelity to the important elements of the image
• More predictable results
• Better understanding of prompts
• Reduction of common errors from previous versions

Improve Render V4 is ideal for elevating the quality of existing images, offering more control, more predictability, and more professional results. The combination of preset improvements and visual indicators makes it easier to choose the right path for each project goal.

Frequently Asked Questions about Improve Render V4

Does Improve Render V4 create an image from scratch?
No. The feature starts from an image you upload. The goal is to improve, refine, or enhance an existing image, such as a render, visual study, or project image.

When should I use Improve Render V4?
Use it when you already have an image and want to improve the visual finish, realism, lighting, or presentation. If you want to create a render from a project image, the more suitable feature may be Render Images.

Do I need to write a prompt?
No. The prompt is optional. You can use just the available improvement types, such as Refinement, Fidelity, Realism, Premium, or Lighting. Use the prompt only when you want to complement the improvement with a specific instruction.

Which option should I use to better preserve my original image?
Use the Fidelity option. It is recommended when you want to improve image quality while preserving as much as possible of the composition, structure, materials, and main elements of the project.

Which option should I use to make the image more realistic?
Use the Realism option. It aims to bring the image closer to a photographic appearance, with improvements in light, materials, shadows, depth, and atmosphere.

Which option should I use for a more sophisticated presentation?
Use the Premium option. It applies a more polished and commercial finish, ideal for presentations, portfolios, social media, and promotional materials.

When should I use the Lighting option?
Use Lighting when the image already looks good but needs adjustments to the light, shadow, or atmosphere. This option is useful for images that are dark, flat, with unnatural lighting, or with low visual contrast.

What do Fidelity and Creativity mean?
Fidelity indicates how much the improvement tends to preserve the original image. Creativity indicates how much the AI can apply interpretations, refinements, and visual changes. These indicators help you understand the expected behavior of each improvement type.

Can I manually adjust the Fidelity and Creativity indicators?
No. The indicators are informational only. Each improvement type already has its own configuration. They are there to help you choose the most appropriate option before generating.

Can I improve an image generated on Redraw itself?
Yes. You can use images previously generated on Redraw and apply Improve Render V4 to refine finishing, lighting, realism, or visual quality.

Does the feature alter the original project?
It depends on the chosen improvement type. Options like Fidelity tend to preserve the original image more. Options like Premium and Realism may apply greater visual changes to improve the finish or presentation.

What type of image can I upload?
You can upload images such as already generated renders, concept images, project studies, images created on Redraw, and visual bases of interior or exterior environments. For best results, we recommend using images with good resolution and a clear reading of the main elements of the scene.

Does Improve Render V4 work for both interior and exterior environments?
Yes. The feature can be used for both interior and exterior environments. The result will depend on the quality of the uploaded image, the chosen improvement type, and any additional instructions added in the prompt, if you use one.

Does the prompt completely change the result?
The prompt helps guide the result, but the uploaded image remains the main basis of the improvement. To maintain more control, use objective instructions such as "preserve the original composition," "improve natural lighting," or "enhance facade materials."

How do I get the best results?
Use high-quality images, choose the improvement type according to the final goal, and when necessary, complement with a simple, direct prompt. Avoid prompts that are too long, contradictory, or that request changes very different from the original image.
