Ok, you're still going to have to play around with the settings. but here's what I did.
You need to make a pattern of a hexagon, the max size for your image. write down the dimensions, it might be helpful. For your image that I increased the size to 2500X1875px, I used a hexagon 51X44.
First, you need to set the offset to .5 under the Brick setting tab. This will stagger each row by half.
Then you need to adjust the spacing. Don't worry about making a referance file at this point, just just the fill so that you can adjust the spacing. I used a X spacing of 31px and a Y spacing of -21px
Next using your test for spacing draw some guides between the enters of the hexagons to get the spacing for your referance file. I used 41px X 24px.
Then enter that number in the UI and click on "Make and Save Reference File" Depending on how big your file is and how small your pattern is, this can take a long time to generate, so be very patient!!!
Once your reference file it done, click on open reference file and open the file that you just created. Click on "Use Ref File, and select, "Scale by density."
Then hit okay. the fill dialog will come up. select script and the script is TempFillScript. Then select your pattern.
Here's what mine turned out like:
Hope this helps.
