Importing and aligning hex kit and other pre-existing maps to the astral grid

Just a short tutorial on importing from hexkit and matching grid size. The same concepts can be applied to square grids or any other pre-existing map that has a grid overlay.

This tutorial uses a 20x20 hex kit export. Grid pixel size is about 179 pixels for a 20x20 (this number was determined by opening the export and seeing how many pixels wide it was) . I just use this number to get us to a close starting point.


  1. Set grid snap to off while aligning
  2. Set a bright background color
  3. Set a grid color that is easy to see…this may mean bright red etc…


  1. Create your new map
  2. (optional) Adjust your starting grid settings based on my advice for hex kit
  3. Import the Hex Kit Image
  4. Align the hex in the top corner (it doesn’t have to be the first hex on the grid)
  5. Zoom out and stretch the import using the right horizontal handle until the top row of hexes match width. (keeping your eyes on the top row only)
  6. Zoom out and stretch the import using bottom vertical handled until all of the hexes match height.
  7. lock your background image to prevent further movement/sizing

That should be it…remember it doesn’t have to be perfect…but 99% is quick and easy to do. Adjust your view/zoom during the process can help. See the video for an example.
