Making a Hex Grid tile correctly

Loren Broach

Hi,

So I'm trying to get a hex grid to tile correctly on a 512x512 texture. I've experimented a lot and I'm starting to think it's not possible. If anyone has a clue how to do this I'd greatly appreciate it.

Does it need to have the 4 different coloured hexes?

It's possible. you need an odd number of hex's horizontally and vertically, which means it may look squished. But this can be fixed within your shader or accounted for in your UVs, I imagine.



and with colors

Does it have to be Hex? Can it be Octo with squares? Because that's a hell of a lot easier, heh.

Thanks guys! Yeah cman2k, I think that is the best solution. For some reason I didn't think about stretching it a little bit and then fixing it in the UV's.

You guys are the best.

Another way, or basically the same way, just stretch it in the UVs indeed:

Sorry to bring this thread back up, but I came across the same problem, and found another solution. Thought I'd share it here for future reference, if anyone else tries to do this.

It's a tricky problem, but by rotating your whole hex-grid 15 degrees (or increments of 15 degrees) it's possible to have a tiling texture with equal-sided hexagons only.
On the left is the actual texture.
This is good mostly for situations where you don't want the tiles to line up with anything specific (otherwise you'll have weirdo UVs most of the time, to align them to the tile angle in the texture), I'm using it for a circular room for instance.

you just need enough of them


EDIT: lol, i just made the same as your first pic

Very clever!
