A collection of high-quality texture utility nodes for technical artists and environment designers. These nodes focus on precision masking and color extraction for emissive materials like Magma, Lava, Neon, and Cyberpunk lighting.

🟢 Emissive Color (Polly)

The flagship node of this pack. Unlike standard brightness-based masking, this node uses HSV Saturation Logic to differentiate between "glow" and "glare."

Key Features

  • Vivid (Lava/Neon) Mode: Prioritizes highly saturated colors. Perfect for grabbing the "orange" of lava while ignoring the "white" of the light source reflection.
  • Brightest Pixel Mode: Traditional luminance-based extraction for standard light sources.
  • Saturation Filter: A precision slider to eliminate grey/white specular highlights from your mask.
  • Color Boost: Intelligently amplifies the detected color to create punchier emissive maps.
  • Manual Override: Use a HEX code or the integrated color picker to force a specific emissive hue onto your mask.

🛠 Installation

Method 1: ComfyUI Manager (Recommended)

  1. Search for Polly in the Install Custom Nodes menu.
  2. Click Install and restart ComfyUI.

Method 2: Manual Git Clone

  1. Open a terminal in ComfyUI/custom_nodes/.
  2. Run: git clone https://github.com/polly-creative/ComfyUI_Polly_Nodes.git
  3. Restart ComfyUI.

📋 Parameters

| Parameter | Description | | :--- | :--- | | mode | Choose between Vivid (Saturation-based) or Brightest (Luminance-based). | | blur_amount | Softens the edges of the generated mask for a natural "glow" falloff. | | mask_threshold | Controls how much of the image is included in the emissive map. | | saturation_filter | Higher values ignore more "white/grey" light, focusing only on pure color. | | color_boost | Multiplier for the intensity of the extracted color. |
