We use Roll20 or Fantasy Grounds, so it is great having a map in JPEG format that can be uploaded into whatever VTT we happen to be using. All of my dungeon maps represent 300' x 300', the same size as the Stonehell Dungeon maps. My scale of choice is each square representing 5'. I find that this scale works perfect with virtual figures or pogs, so that the map can double as an online battlemap. The map above (Map A) is actually a composite of four JPEG files.
For regular dungeon features, I draw straight lines and use the AutoREALM snap grid feature to line them up with the grid. I use the draw polygon function to fill in the spaces between the rooms/corridors. For caverns and other irregular features, I use the freehand drawing feature and draw closed shapes. I keep doing that until I get the features I want. You can see the results of both methods on Map A above.
In order to publish the maps on my blog, I first create a Publisher file and line up the JPEG map files next to each other. Then I draw and fill black squares to cover up the unexplored areas. I save the resultant map as a JPEG file and crop it. That is how I created Map A above; it is a composite of four separate JPEG maps with the unexplored areas covered and cropped.
Other AutoREALM Maps
I am not particularly good at creating maps in AutoREALM, mainly because I haven't spent enough time playing around with it. I created the following maps for my Castles & Crusades Emmon Campaign.
|Map C: Elbow Bay|
|Map D: Sali Isle|
|Map E: Village of Melford|
