Creating Day and Night Scenes

Answer

Short answer:

Yes, you can create scenes for any time of day, including bright daylight, golden hour, or night. You control the lighting through text prompts, reference images, or by applying specific styles to your base input.

Overview

Lighting is one of the most critical components of architectural visualization. It defines the mood, highlights material textures, and helps clients understand how a space functions at different times.

In Rendair AI, lighting is not a manual setting where you place individual suns or lamps. Instead, the AI interprets the desired atmosphere from your description or reference image. This allows you to rapidly visualize a single design in multiple lighting conditions, switching from a sunny afternoon to an evening interior, without needing to adjust render settings or re-calculate global illumination manually.

How it works

There are two main ways to control the time of day in your visuals:

Text Prompting

When describing your scene, include specific lighting keywords. The AI uses these to calculate shadows, reflections, and color temperature.

• Example: "Modern concrete villa, sunny day, clear blue sky."

• Example: "Cozy living room, night time, warm interior lighting, city lights in background."

Reference Styles

If you have an image that captures the exact mood you want (for example, a specific "blue hour" photograph), you can upload it as a reference style. Rendair AI will apply the color palette and lighting characteristics of that reference to your design.

Capabilities

You can generate a wide range of atmospheric conditions to suit different stages of the design process.

• Daytime rendering: Ideal for showing clarity, material colors, and landscaping. You can specify "overcast," "bright sun," or "soft morning light."

• Night rendering: Focuses on artificial lighting, interior warmth, and exterior facade lighting. The AI automatically simulates light spilling from windows or fixtures.

• Golden hour: Creates long shadows and warm, orange hues, often used for marketing materials to evoke emotion.

• Seasonal changes: Beyond time of day, you can combine lighting with seasonal prompts like "snowy winter evening" or "rainy autumn afternoon."

When to use this

• Client presentations: Show the client how their home feels during a dinner party versus a Sunday morning.

• Real estate marketing: Use "golden hour" or "dusk" shots to make listing images stand out, as these often perform better in marketing feeds.

• Lighting studies: Quickly assess where shadows fall or how artificial lights impact the facade without setting up complex IES profiles in 3D software.

Limitations or notes

• Artificial lights: In night scenes, the AI infers where lights should be based on the image context (e.g., ceiling spots, lamps). It does not allow you to manually place a specific bulb with a specific wattage.

• Consistency: If you need the exact same camera angle for a day-to-night transition, ensure you use the same base image (sketch or 3D screenshot) and only change the prompt.

• Reflections: Night scenes rely heavily on reflections. Ensure your base geometry or sketch clearly indicates glass surfaces so the AI understands where to reflect the environment.
