ComfyUI-ShaderNoiseKSampler

ComfyUI-ShaderNoiseKSampler is an advanced custom KSampler node that blends standard noise generation with a multi-stage shader-based system. Unlike traditional sampling that teleports randomly between different seeds, this tool provides a structured vehicle for exploring the neighborhood around a chosen seed, using mathematical patterns to navigate along coherent paths through latent space.

[!TIP] Perfect for artists and researchers looking to explore the latent space with more intention, sculpt image features with mathematical precision, and achieve unique visual styles through deliberate exploration rather than random discovery. (Using a fixed seed is key to this deliberate exploration, allowing you to systematically investigate the variations around a chosen starting point.)

[!IMPORTANT] The Shader Noise KSampler contains a shader display and requires saving, while the Shader Noise KSampler (Direct) does not contain a shader display and does not require saving. The shader display will help you better understand the parameter controls visually, while the (Direct) version is better for ideation and enables finer control over input values.

🚀 Recent Updates

• Comparer Auto-Fill - 6/12/25: Both the Advanced Image Comparer and Video Comparer nodes now feature an auto_fill toggle. This addition streamlines your workflow by allowing you to compare with a single input. When auto_fill is enabled (the default setting), any empty image or video slot will be automatically populated with the output from the previous generation. This makes iterative A/B testing—comparing your latest creation to the one right before it—faster and more intuitive. It does not pull from your output folder but from the cached images or videos of your current session. Video Comparer Updated WEBP

🧭 Navigating the Seed Universe

Think of standard image generation, where you try different seeds, as driving from one town to another. Each new seed takes you to a completely different town.

The ShaderNoiseKSampler works differently. It's like picking one town (one specific seed) that you find particularly interesting, and instead of just driving through to the next one, you decide to stop, get out of the car, and really explore that specific town. You can wander down its hidden alleyways, check out its diverse neighborhoods, and discover all the unique details and variations it holds.

The shader noise is your map and the shader parameters (like Noise Scale, Octaves, Warp Strength, etc.) are your compas
