Yea, it's fine. I'm just going to link yours to the Iron Forge since it is below it, so I consider that an entrance.

Welcome.

Sure thing. Happy mapping.

Shadows are applied to all entities on the sheet with the effect. If you need some walls to not cast shadows, you need to place them on other sheets.

Note of course that you can have all your walls on a non-shadow sheet, and then just double up with a new set of walls on the shadow sheet so you don't have to break apart the rooms. The "walls" casting shadows could actually just be thing black lines on a dedicated sheet.

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 Note that the accompanying data file is a bit out of date, so a lot of files will be identified as unknown add-on.
