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.

📋 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.
