IC Light Illumination Control Workflow

IC Light node collection is a set of tools specifically designed for image illumination control. Its core function is to achieve natural image blending by adjusting the consistency between foreground and background lighting.

Multi-dimensional Illumination Adjustment

Supports four-directional light source control (left/right/up/down) and color atmosphere adjustment. The Lighting Preference parameter allows precise specification of light direction.

Text-based Condition Mode (FG Workflow)

Generates background lighting based on text prompts. By inputting keywords like neon light effects or sunlight, the system can reconstruct complex light-shadow relationships.

Background-based Condition Mode (BG Workflow)

Extracts lighting information by inputting a background image and automatically matches foreground lighting (this workflow uses the iclight_sd15_fbc.safetensors model).
