Today, we’ll walk you through how to use the latest v4.1 engine for your exterior design projects. This guide covers the essential steps to help you get the most out of Exterior AI with v4.1. You can access v4.1 through either the Exterior AI Legacy Tool or the Studio interface, both of which can be selected from the top-left corner of the design interface.
Interface Walkthrough
Before jumping into a sample, let’s take a quick look at the new engine interface. For this guide, we’ll be using the Studio interface.
At the top-left corner, you’ll find the engine options, where you can easily view and select from all available engine versions.
Next, you’ll find the Expert section, where you can choose options to classify your project type. The Expert setting simply defines what kind of project you’re working on, such as Exterior, Interior, Masterplan, and more, helping the engine generate more accurate results.
Below that, you’ll see the Camera options, which include two sub-settings: Rotate and View. Here, you can choose the angle for generating your image, whether you want to keep the original view or switch to a different perspective, such as a low angle or top view. This is one of the key upgrades introduced in v4.1, giving you more control over your final output.
Another new addition to the built-in options is the Scene Element section. Here, you can add various elements to enhance your design, such as cars, trees, and people. If the element you need isn’t listed, you can simply type it directly into the prompt box, giving you full flexibility to customize your scene.
Below that is the Lighting section, another upgraded feature of mnml.ai. This allows you to set the atmosphere based on the time of day. Commonly used options include Daylight, Night, and Golden Hour, making it easy to control the mood and overall feel of your render.
After setting the lighting, you can move on to the Render Style section. Here, you’ll choose the overall look of your render. While Realistic is the most commonly used style, you can also explore other useful options like CGI or Sketch to suit different presentation needs.
The second-to-last section is the Geometry setting, which includes two important options that can greatly affect your final render. Choose Precise to maintain accurate geometry, or Creative for a more flexible and expressive output.
At the bottom, you’ll find the Reference Images option. This feature helps guide the render toward the exact style you want to achieve. You can upload up to four reference images to improve consistency and better align the output with your vision.
To complete your render setup, head to the prompt box and select a Scenario. You can choose Render for a more precise and controlled output, or Edit if you want a more flexible and creative result.
Once you’ve set your preferred parameters, simply click the Render button and wait a few seconds for your design to come to life.
