[Introduction]

In the field of AI-powered image transformation, indoor design visualization has become an essential tool for designers, architects, and homeowners. The Indoor Design Style Switch workflow in ComfyUI utilizes ControlNet and BrushNet to intelligently transform indoor spaces, offering a seamless way to explore and experiment with different interior design styles. Whether you’re looking for inspiration, presenting a design concept, or envisioning a home makeover, this workflow makes it possible with just a few clicks.

Core Technologies in Indoor Design Style Switching

This workflow leverages a combination of AI-driven preprocessing, depth mapping, and color enhancement to modify indoor space aesthetics. Below are the key components that enable this transformation:

1. ControlNet for Structural Guidance

ControlNet is a powerful AI framework that helps maintain structural integrity when applying artistic transformations. In this workflow, two ControlNet preprocessors are utilized:

LineArt Preprocessor: Converts the original indoor image into a detailed line drawing, capturing the key structural elements of the room, such as walls, furniture, and decor.

Zoe Preprocessor: Generates a depth map to provide spatial awareness, ensuring realistic depth perception and object positioning.

These preprocessors work together to preserve the original layout while allowing for stylistic modifications.

2. BrushNet for Texture and Color Application

BrushNet plays a crucial role in applying textures and colors that align with the desired style. After processing the image with ControlNet, BrushNet takes over by:

Enhancing materials, such as wood, metal, and fabric surfaces.

Refining shadows and highlights to create a more immersive lighting effect.

Blending elements naturally to ensure that the updated design does not look artificial.

By passing the image through BrushNet, the workflow ensures smooth and visually coherent transformations that match the selected style.

3. Prompt-Guided Customization

A key feature of this workflow is its ability to accept user-defined prompts to dictate the desired style. Users can input descriptions like:

“Bright, sunny, spacious, herbal natural style theme, high-end color scheme, sofa, carpet, blanket, seating, table, lighting.”

“Minimalist, monochrome, modern, sleek, open space, glass walls, neutral tones.”

“Cozy, warm, wooden furniture, soft lighting, vintage decor, rustic ambiance.”

These prompt words guide the AI model (General Style epiCPhotoGasm V1.safetensors) in generating a context-aware, aesthetically pleasing design transformation.

Application Scenarios

1. Interior Design Inspiration

This workflow is ideal for interior designers looking for quick style variations before committing to a final concept. By experimenting with different themes, designers can gain insights into color schemes, furniture arrangements, and lighting effects.

2. Home Decor Planning
