1. Workflow Overview

This is an IC-Light V2-based advanced lighting control workflow designed for:

• Dynamic Lighting Synthesis: Precisely adjust light direction, intensity, and color gradients.

• Style Transfer: Migrate lighting styles from reference images via IPAdapter.

• Cinematic Post-Processing: Includes detail enhancement, color blending, and sharpening.

2. Core Models

3. Key Nodes

Dependencies:

• IC-Light Model: Place iclight_sd15_fc.safetensors in models/unet.

• IPAdapter Model: Download ip-adapter-plus_sdxl_vit-h.bin to models/ipadapter.

4. Workflow Structure

• Group 1: Lighting Control & Style Transfer

  • Input: Reference image + lighting parameters (e.g., intensity 0.182).

  • Output: Latent data with lighting conditions.

  • Key Nodes: ICLightConditioning, IPAdapterAdvanced.

• Group 2: Image Generation

  • Input: Conditioned Latent + prompts (e.g., "cinematic sunlight").

  • Output: Initial generated image.

  • Key Nodes: KSampler (uses dpmpp_2m_sde sampler).

• Group 3: Post-Processing

  • Input: Raw output + reference image.

  • Output: Final image after detail/blending/sharpening.

  • Key Nodes: DetailTransfer, ImageBlend, ImageCASharpening+.

5. Input & Output

• Input Parameters:

  • Image: Reference (e.g., portrait).

  • Prompts: Positive (e.g., "cinematic sunlight") and negative (e.g., "low quality").

  • Lighting: Default intensity 0.182 (adjustable via ICLightConditioning).

• Output: Final image (PNG) + comparison view (Image Comparer).

6. Notes

• VRAM: ≥10GB GPU recommended (IC-Light + IPAdapter are resource-heavy).

• Common Errors:

  • Missing IC-Light model triggers red error alerts.

  • Overexposure if light intensity > 0.3.

• Optimization:

  • Use FreeU_V2 for quality boost (params: 1.5, 1.6, 0.9, 0.2).

  • Reduce KSampler steps (e.g., 30 → 20) for faster generation.
