As AI-powered image generation becomes more integrated into architecture and interior design workflows, it’s no longer enough to simply generate images. You need to know which tool to use and when to use it. Whether you’re visualizing a fully modeled building or experimenting with a rough sketch, matching the right AI tool to the stage of your process can dramatically improve both speed and results.
In this post, we’ll walk through the three main AI function types in Planby Studio: Render Interior/Exterior, Virtual Renovation Mode, and Smart Blend/Partial Edits. We’ll explain when to use them, what they’re good at, and how much creative control they allow. We’ll also point out common mistakes to avoid, and compare each mode to Stable Diffusion’s ControlNet, giving you a clearer sense of how each model interprets your input.
Creative Freedom: Low (≈ ControlNet Weight 0.8)
Render Mode is designed for precision. If you’re working with a detailed 3D model from Revit, Rhino, or SketchUp, this is the tool that will translate your vision into a polished, photorealistic output. It’s best used when accuracy matters more than exploration.
This tool works like applying a high ControlNet weight on Stable Diffusion. The AI sticks closely to your input, making only subtle enhancements. It’s ideal when control is more important than creative interpretation.
Virtual Renovation Mode allows the AI to reinterpret your input more freely. If you’re experimenting with broad design directions, this is where you start. It works particularly well when your inputs are loose, and you’re looking for new possibilities rather than polished output.
This tool works like applying a low ControlNet weight. The AI uses your input as a rough guide and makes broad, creative decisions. It’s perfect for exploring early concepts and stylistic variations.
Creative Freedom: High (≈ Denoise Strength 1.0)
Smart Blend allows you to edit specific areas of a render while keeping the rest of the image intact. It’s an efficient tool for fine-tuning without restarting the generation process. Simply select the region you want to modify and describe the change; the model handles the rest.
These function similarly to inpainting or masked editing. Only the selected region is regenerated. The AI blends new content into the existing image with natural transitions, making it ideal for iterative workflows.
Model | Recommended For | Creative Freedom | Comparable ControlNet Weight | Output Style |
Render Exterior / Interior | Finished 3D models | Low | ~0.8 | Accurate, realistic, input-driven |
Virtual Renovation | Sketches or early design ideas | High | ~0.3 | Creative interpretation, conceptual |
Smart Blend / Partial Edit | Editing specific parts of images | High | N/A (Inpainting-style) | Specific edits with natural transitions |
While each AI model in Planby Studio has a clear purpose, they’re not locked into a fixed sequence. Our tools are designed to be intuitive and flexible, so you can use them in the order that best fits your workflow.
Some projects may start with a rough sketch and evolve through rendering modes, followed by Virtual Renovation or Partial Edits for a polished final image. Others might begin with a fully developed render and use Smart Blend later for small iterations or localized changes.
There’s no one-size-fits-all path, and that’s intentional.
Each tool is made to support different types of thinking: exploration, refinement, presentation, or editing. You’re free to enter the process at any point, switch directions, or use tools independently to achieve your specific creative goals.
Choosing the right tool in Planby Studio isn’t just about your current input; it’s about what kind of output you need next. Use Render Interior/Exterior when you’re ready for presentation-level quality. Switch to Virtual Renovation when you’re exploring big ideas or mood concepts. And turn to Smart Blend when it’s time to polish details without starting over.
Understanding the strengths and limits of each model is key to working faster, producing better results, and unlocking the full potential of AI-assisted design. Now that you know what each tool is for, you can stop guessing and start creating with intent.
