Use AI to Create Image Precisely
This section explains how to efficiently generate images that closely match your design intent in iCraft using the AI Render Export feature. By combining geometric placeholders + color differentiation + precise prompts, you can quickly create highly relevant scene images—even without advanced 3D modeling experience.
Core Concept
AI image generation in iCraft is not based on pure imagination. Instead, it relies on the following inputs:
The current scene composition and camera view
The position and scale of geometric objects in 3D space
Color tags representing different objects
The prompt provided by the user
The system synthesizes all of this information to generate the final rendering.
Therefore, achieving controllable, accurate, and expected results does not depend on writing random descriptions. Instead, the key is:
👉 Use geometry to build spatial structure, colors to create semantic labels, and prompts to map objects precisely.
Workflow
Build the Spatial Structure Using Geometric Shapes
In the editor, do not rush to use complex models. Instead, begin with basic geometric shapes (such as cubes, cylinders, and spheres). Place them according to realistic proportions to simulate objects such as walls, equipment, furniture, cabinets, pipelines. Make sure the spatial relationships (distance, height, orientation) are logical.
Additionally, it is recommended to use colors as semantic labels. Assign different colors to different geometric shapes so they can be distinguished in prompts. These colors are not the final visual appearance, but rather visual hints for the AI.
At this stage, focus on:
✅ Reasonable layout and accurate proportions ✅ Clear composition ✅ One distinct color per object category ✅ Avoid similar colors (e.g., dark blue vs. light blue) ✅ Prefer highly distinguishable color blocks
Define the Camera View and Composition
Before using the AI rendering function, make sure to:
Create a fixed camera view in the camera panel
Adjust focal length and camera height
Choose the best perspective
Ensure the main subject is clear and unobstructed
Maintain a balanced composition
Recommendations:
Use a slight top-down perspective to present the overall layout
Avoid extreme wide-angle lenses
Ensure key objects are located near the center of the frame
Once the composition is finalized, the AI image generation will use this view as its base.
Use AI Render Export
Click AI Render Export in the export panel to enter the image generation interface. You will need to enter a prompt in this interface. You can extend the preset prompt with additional custom requirements.
Example:
Select the preset “Realistic Style”, which automatically fills in the prompt:
Realistic style, ultra-realistic rendering, 8K ultra-HD detail, HDR dynamic range imaging, micro-surface textures and reflective gloss, realistic depth of field, natural lighting and ambient light, accurate color reproduction, physically based lighting simulation, sharp edges and details, professional photography composition, minimalist aesthetics.
Then add additional prompt instructions:
I want to generate this scene as a coffee bar corner. The yellow cylinder represents a coffee machine. Several blue cylinders represent a coffee grinder, coffee cups, and coffee accessories. The green cubes represent storage cabinets and wine cabinets beside the bar counter. The purple cubes represent decorative plants near the bar counter. The brown cone above represents a warm yellow hanging lamp. The overall scene should feel soft, relaxing, and lifestyle-oriented, with warm lighting, a gentle atmosphere, Instagram-style aesthetics, high-definition photography, and a cozy home environment.
Combined into the final prompt:
I want to generate this scene as a coffee bar corner. Realistic style, ultra-realistic rendering, 8K ultra-HD detail, HDR dynamic range imaging. In the scene, the large black rectangular block represents the coffee bar table in a natural wood style. The yellow cylinder represents a coffee machine. Several blue cylinders represent a coffee grinder, coffee cups, and coffee accessories. The green cubes represent storage cabinets and wine cabinets beside the bar counter. The purple cubes represent decorative plants beside the bar counter. The brown cone above represents a warm yellow hanging lamp. The overall scene should feel soft and comforting, a lifestyle-oriented setting with warm lighting, a gentle atmosphere, Instagram-style aesthetics, high-definition photography, and a cozy home environment.
System will generate the image based on:
the current scene screenshot
scene depth and geometric relationships
the user prompt
If you are not satisfied with the generated result, you can regenerate the image or perform localized edits directly on the generated result.
