FLSampler (BSS) for ComfyUI 🔬

A high-performance custom sampler inspired by the physiology of human sight (**Foveated Vision**). Engineered to deliver stunning cinematic clarity, rich micro-textures (skin, hair, fabrics), and precise depth-of-detail control inside the latent space—with zero performance overhead.

> ⚡ Ultimate Speed & Quality Combo:

> To achieve the ultimate balance of breathtaking visual clarity and extreme speed, we highly recommend pairing this node with our optimization suite ANIMA_BOOSTER

🔬 How it Works

Instead of uniform denoising, FLSampler selectively enhances latent focus zones:

Differential Latent Analysis: Dynamically tracks where structures and object boundaries are forming.

Local Contrast (Sharpness Boost): Unsharp-masks active focus zones directly in latent space for ultra-sharp details (safe default 0.5, range 0.0–3.0).

Stochastic Texture Injection: Adds controlled micro-noise to focus areas, naturally resolving into skin pores, clothing fabrics, wood grains, or hair, preventing flat plastic surfaces.

BSS Premium UI: Integrated dark-matte & gold custom theme.
