I advise picking names like block-a2, block-b1, etc. Repeat this process for each of the blocks.

Antialias: 33% (or whatever suits your style).Resolution: 25 (though I don't think this actually matters).click BMP, JPG, PNG from the Import/Export Options.Since I want these 500' x 500' blocks to be exactly 5 pixels per foot, 25 pixels per 5', the export needs to be exactly 2500 x 2500 pixels. recommend selecting a more visible Grid Dot Style so it is easier to see.right click on Grid, Ortho, or Snap to bring up the "Select Grid System" dialog.In CC3+, I created a grid so that I could use snap points to more easily export (Save As.) the sections of the map. At least on my setup, CC starts to take a long time to render and MapTool begins to choke and chug. I would advise against individual images larger than 2500 pixels. For example, you could have the 2500 pixels represent 250 feet for 50 pixels per 5'. for a dungeon map, just adjust the numbers as you see fit. Therefore 5 pixels per foot (25 pixels per 5') in MapTool. I decided to use image files that were 2500 x 2500 pixels that represented 500 x 500 feet.

Since this is for a city campaign, I was more interested in something that looked good at a distance, but would also suffice as a grainy battle map. I wanted to have a big map with reasonable detail. Getting blocks to be the exact size so they could be seamlessly stitched together was the biggest challenge. In short, I created a grid to make it easier to export blocks of the map and then placed those images in the background layer of MapTool. So I figured I would share what I did in the hopes that others may benefit and some of you may be able to provide pointers for improving my process. The other threads I found on this topic were sparse and outdated. It has been a while since I used Roll20, but I recall the process and believe it would be similar. I have recently begun using Campaign Cartographer (with City Designer 3) for creating my maps and wanted to find a way to export my maps to use in MapTool. I have a digital setup and use MapTool (v1.5.4) from for running my games.
