Answer

Short answer:

You can generate new design alternatives in approximately 10 to 30 seconds per iteration. By using features like Batch Generation (available on Pro plans), you can explore four distinct design directions simultaneously, reducing the feedback loop from days to mere moments.

Alongside batch generation, you can have up to 10 generations processes running at the same time.

Overview

The shift from linear to concurrent design.

In traditional workflows, iteration is a bottleneck. Changing a material or lighting condition requires re-texturing, re-lighting, and re-rendering, a linear process that can take hours or days. This latency forces architects to commit to decisions early, often before they are fully tested, simply to meet deadlines.

Rendair AI removes this penalty. Because the rendering engine is generative rather than physical-based, it does not "calculate" light paths in the traditional sense; it predicts them. This allows you to treat visualization as a sketching tool rather than a final documentation step. You can test a "concrete facade" against a "timber cladding" option in the time it takes to type the words, allowing you to present clients with a menu of possibilities rather than a single, fragile guess.

How it works

1/ Define your base

Start with a simple input. This can be a text prompt, a rough hand sketch, a massing model screenshot, or an existing render you want to change.

2/ Generate variations

Use the Image and Creativity Strength slider to control how far the AI deviates from your input.

• Low Creativity (0-30%): Keeps the structure identical; changes only materials and lighting.

• High Creativity (60-90%): Explores new forms and architectural geometries while keeping the general composition.

3/ Select and modify

Instead of re-rendering the whole image, use the Editing (Select & Modify) tool. Highlight a specific area, like a window or a roofline, and type a new prompt (e.g., "floor-to-ceiling glass"). The system updates only that section in seconds, blending it perfectly with the rest of the image.

Capabilities

What you can do in under a minute

• Material Studies: Instantly swap brick for stone, wood for metal, or plaster for concrete across four simultaneous generations.

• Environmental Context: Test your design in different seasons (winter snow vs. summer sun) or times of day (golden hour vs. overcast) to see how the mood shifts.

• Massing Options: Upload a basic block model and generate multiple architectural styles (e.g., Brutalist, Scandinavian, Industrial) to find the right aesthetic direction.

• Rapid "Fixes": Remove unwanted site elements (like cars or trash cans) or add entourage (people, vegetation) without opening Photoshop.

When to use this

• Client Meetings: Generate alternatives live during a conversation when a client asks, "What would that look like in wood?"

• Feasibility Studies: Quickly visualize massing options on a site photo to understand scale and impact.

• Internal Reviews: Bring 10 different options to a team meeting instead of one, preventing the "we need to go back to the drawing board" delay.

• Value Engineering: Visually demonstrate why a cheaper material might not achieve the desired premium look, or find a cost-effective alternative that does.

Limitations or notes

• Queue Times: Users on the Creator plan may experience wait times during peak hours. Pro and Team Pro users always skip the queue.

• Consistency: While fast, generative AI can sometimes hallucinate details (e.g., misaligned windows). Use the "Fix" tools or lower the Image Strength to rein in the model.

• Resolution: Fast iterations happen at lower resolutions (~1MP). Only upscale to 4K+ once you have selected the winning design to save time and credits.
