Affine Checker Noise Options

The checker pattern in WAS Affine does exactly what it sounds like: it builds a checkerboard mask, alternating on/off squares, and the affine effect lands only on the bright tiles. Affine Checker Noise Options is about the simplest node in the whole pack - one input, one DICT output.

The knob

• checker_size (default 6) - size of each checker square in pixels. Small values (like the default) give a dense, fine texture; larger values give big obvious tiles.

That's it. Output: a noise_options DICT wired into the noise_options input of Latent Affine, an affine sampler, or Affine Pattern Noise.

When you'd use it

Honestly, a pure checker is a niche mask - it's the pattern you pick when you want a visible, mechanical alternation: test renders to see exactly where the effect lands, stylized "pixel grid" looks, or A/B sanity checks of the affine math itself. The README files it under "geometric patterns," alongside bayer and solid, and suggests geometric masks for architectural/geometric work. Most of the time you'll get more natural results from perlin or a noise pattern, but when you need to see the mask working, a checker makes it unmistakable.

The single knob means there's no real tuning curve: set a size, wire it, preview the mask output from Latent Affine, done. If you want checker squares with softened edges, add blur via the common options - that combination is how you get from "hard grid" to "subtle grid," which is usually the look people are actually after.

Common issues

The one trap: a hard checker at large sizes leaves zero-falloff edges, and in latent space that can produce visible tile boundaries in the output. If you see a grid in your image that you didn't ask for, that's the mask showing through - shrink checker_size and/or blur it in the common options. And as always, the node is inert until its DICT is connected.
