I suspect that the structure shading has slipped somehow for the symbols that are showing purple. Try hiding the layers called STRUCTURES (SHADING), and STRUCTURES (OUTLINE).

You are mostly there with the transparency acne separation sheet, but instead of using a new polygon on that sheet, copy the actual grass polygon onto that sheet and use change properties to turn it solid and whichever blue colour you are using. Copy the EFI effect from the paler grass to the separation sheet, and edit it slightly to make it wider than it is on the grass sheet.

If there is transparency acne happening between the blue and the grass, try using colour 227 instead of that blue. The exact colour of that polygon only needs to be a colour that definitely isn't included in the overlying grass texture, not even as a single pixel.

Here are a few extracts from the finished example map for the June issue of the Cartographer's Annual. The map is a bit large, so I'm not sure if it will be the final example map since a normal sized render doesn't really show the details. These are taken from an 8000 px render.

However, I can say that there will definitely be a smaller part 2 to this style in August, so I'm open to suggestions for additional symbols to fill out the set. Most things are shown, though I forgot to use the tree roots.

I have just put these in my gallery here.

Focussing on the Cartographer's Annuals in this response - most recently this month's edition of the 2022 CA (Electronic Systems) might interest you. https://www.profantasy.com/annual/2022/2022-cartographers-annual.asp#May I mentioned this one issue specifically because I haven't updated the annual links wall to include it just yet, but the majority of all the rest of the annual issues can be browsed from here:

There are other add ons and packs, including Cosmographer, which might also be of interest.

Looks like a good little map. Let us know how it went down :)

I can't help but think that I've gotten slightly side-tracked with portals and things, but it was fun.

Those are will-o-wisps, by the way ;)
