Great. Only the dungeon levels are applicable for the competition obviously, but the overland map is great to be able to position the dungeon in the atlas.

You can run the LISTIMAGENAMESDWG command to do this. It will list all the images in a drawing, and tell you if it is a fill style image (bmpsty) or a symbol/inserted image (pictr2)

You can also use my custom command that list images sorted by addon. Note that the accompanying data file is a bit out of date, so a lot of files will be identified as unknown add-on.

Would love to see it in the atlas ,both the overview map and the battlemaps.

But yea, you would have to change the names. I'll also need you (or someone else) to find a location in the atlas where it will fit and look like it belongs, and the names would then probably have to be changed to match the location you place it.

1. The reason it gets partially cut off during export is the export setting 'Restrict image to map border'. The map border here is the actual map border (a thin line) and not the decorative one. You can avoid this by turning off this option, but it will probably also result in some white borders around the map. You can also use the rectangular section export file type when exporting, which lets you precisely control the export area yourself.
2. This is an issue with how sheet effects work. When they look for the edge to put the glow around, the way this edge is identified is by finding the difference in the image with this sheet on top compared to the one without. But if the pixels on the sheet below contain exactly the same color, as it happening here with the black outline of the trees matching the color of the text, the effects processor sees this as no change, and considers this an edge. Try changing the color of your text to the darkest gray instead of black.

From personal experience, having part of a map that you must name yourself is always a poor experience, it is so much easier to use a pre-made map if it has names.

Of course, not every minor street in a city map needs to be named, but having a good chunk of them named is always very helpful.
