Tessera AntiTiler

Break visible texture repetition on large surfaces with variance-preserving

stochastic sampling — the contrast stays, the grid goes. URP and HDRP,

triplanar and biplanar, Unity Terrain splatmaps, height, histogram, macro and

detail blending. Six drop-in shaders including Unity Terrain; Shader Graph

optional.

The problem

One ground texture, tiled a hundred times, reads as a grid. The eye finds the

period in seconds and then sees nothing else. The usual answers all cost

something: more textures cost memory, decals cost draw calls, bigger textures

only move the problem further away.

The approach

Stochastic sampling splits UV space into a triangular lattice and reads the

texture once per cell with its own random offset — and, optionally, its own

rotation. Three of those taps are blended barycentrically.

That alone makes the surface flat, because averaging independent random

variables shrinks variance. This asset computes exactly how much was lost and

puts it back, rather than hiding it:

```

result = mu + (blended - mu) / sqrt( SUM wi^2 )

```

The gain bounds itself. Where one tap dominates, `SUM wi^2` is 1 and nothing is

touched. Where three taps meet equally it is 1/3, so the gain is sqrt(3) — the

most the blend can ever need. Nothing is hand-clamped.

That is why a blend band here looks like more of the same material instead of a

soft patch. Measured: local RMS contrast inside the blend band is 1.035x the

contrast of the dominated core. With the correction switched off, the same

measurement reads 0.78.
