That's right.

If it's on the WALLS sheet and layer it will behave correctly when doors, windows and other cutting symbols are used.

You're welcome :)

No. On doesn't connect the lines.

Your effects aren't broken. They are just scaled really tiny - so tiny you can't even see them.

I've just been through the whole set and discovered that you have them all set to Percent of Drawing Extents Width as the Effect Units. This means that whatever figure you had in the Edge Width box (these were also really tiny before I started on the map) is only that percentage of the map width.

I've changed them all to Map Units and given them about 10 map units Edge Fade Inner. I've also moved that piece of scrubland fill to the TERRAIN DESERT sheet because it was on the same sheet as the grassland behind it. That was why it wouldn't edge fade.

You will probably still need to adjust them all to suit your taste, but at least you are on the right track now.

To edit a sheet effect you need to pick the sheet in the list on the left and then pick the effect you want to edit and click the Edit button on the right.

I think the rock fill is possibly a little bit too busy. If you swap it out for a texture that doesn't have quite so much texture in it the rest of the map will stand out a lot more clearly.

Otherwise, good work :)
