You did that in the material editor? I really need to dig into that system! Between this and the water material stream I watched the other day, I would say the material editor can do way more cool things than I even thought possible.
By looping you mean that the above is static and doesn’t update as you move around, or that it would be harder to get the left and right edges to meet up? Really in this case I just need the left side to wrap around to the right side, then I could just swing the camera around it and I would be pretty much set.
Is there much difference in implementation for hexes(math?), or would it be the same?
