Aligning Hex Grids

[7H3LaughingMan]

Alright, I figured it out by doing some math. I am going to post this so that other people can get some help with how to properly align Hex Grids.

First you are going to need the length of one of the sides. You can make some number up if you are making a map from scratch, for my example I chose 30 pixels to be the side length for my hexagon. Next you are going to need to bust out a calculator and do the following calculations.

Hexagon Height = 2 * sin(60) * Side Length
Hexagon Width = Side Length + cos(60) * Side Length * 2 (Remember your order of operations!)

When I use a side length of 30 pixels then I end up with a Hex Width of 60 and a Hex Height of 52. Plug those numbers into Hexographer and do a "Export Current Size as PNG Image". If you choose one that includes resize it is going to ignore the width/height we chose and use the default one it uses. Then you need to crop the image since it adds some extra bits on the sides usually and put it into Fantasy Grounds.

After all that is done you can draw the hex grid as usual, and to make it easier to get the right size just expand it till you get the number equal to the height. So when I was drawing it the hex size was 52. Once that is done you just need to align the grids and it was perfect!

Glad you got it working with a bit of maths!

To simplify your two equations:

Hexagon Height = Side Length * 1.73
Hexagon Width = Side Length * 2

Hexagon Height = 2 * sin(60) * Side Length
Hexagon Width = Side Length + cos(60) * Side Length * 2 (Remember your order of operations!)

This is why I gave up

Hexagon Height = Side Length * 1.73
Hexagon Width = Side Length * 2

This I can deal with

Hey folks. I did a calculation of which combination of hexagon width and heights were closest to whole numbers. You can see the calcs here.

But the best combinations are...

97 height by 112 width
265 height by 306 width
418 height by 361 width

I'm unsure how this affects file size. Hope this helps others in the future.

Worldographer, the new Hexographer, does allow you to specify the width and height of your hexes.

Edit: Setting 49 height and 56 width for row-based hexes created a FG friendly map.

Excellent, I was having a heck of a time getting the hexes to be regular from Hexographer. This procedure worked finally for me except I swapped the hex height (60) and width (52) since I'm rolling with aligned hex rows instead of aligned hex columns. Thanks!

You can turn off the grid in Hexographer before export. that way it will export an image without the grid lines.

True, but that defeats the purpose of what I'm doing with it. The method outlined above allows for keeping the grid lines in the original image generated by Hexographer 1.

Now if only the hexes drawn by Fantasy Grounds weren't made out of fat jagged lines...

I would really love it if you could set a grid (square or hex) and then make it invisible (leaving only the grid lines on the map image, or none.)
