> Using hex-tiling allows us to hide the repetition but requires a solution to hide the seams between adjacent hex tiles. I don't understand this part. If I use square tiles and hide the seams between adjacent tiles, will it look OK? What's the benefit of using hex tiles?

You don't get the typical visual repetition of features along X/Y lines

  You could use world position (or just some non-uniform sampling) to offset the UVs and get a similar effect, no? Is hex significant or is it just one of any number of ways to break up the uniformity?

    In practice, yes, it's very common to use a shader to sample the texture with some rotation and noise. Most games have a shader level implementation to address this, and we've done that for a decade at least. See: https://iquilezles.org/articles/texture https://iquilezles.org/articles/texture repetition/ for a good breakdown on some techniques.

> If I use square tiles and hide the seams between adjacent tiles, will it look OK? Square tiling is very obvious, as you can see from the first example [0]. Hex tiling shifts tiles to a less obvious pattern. Also, as I can see from the video, tiles can be rotated while hiding the seams perfectly, which eliminates repetition altogether. 0. https://github.com/mmikk/mmikk.github.io/blob/master/pictures/hex_demo/colorhextiling.png https://github.com/mmikk/mmikk.github.io/blob/master/picture...

  Is that first example comparing squaring filing with the same _fixed_ rotation for each tile versus hex-tiling with random or otherwise varying rotation?
