That was 8 years ago, now. Today we have a lot more commands for things like this.

The shortest way is just to add the missing bit if there is a gap, hide all other sheets but the LAND sheet, pick the properties of the land, and then use the keyboard command TRACED to select them all and join them all into one by automatically tracing all the way around the whole lot. Delete the separate bits of land and you will be left with just the one part.

That looks like an interesting map :)

There are lots of different ways of doing a glow, so I will tell you mine, and others will probably tell you theirs. Which you use is up to you.

I would draw the purple polygons with a smooth poly on their own sheet, and on that sheet I would add a reasonably large blur to soften the edge, and then a Blend Mode set to Screen.

If you are interested in creating a heatmap Jason Payne wrote a good article on that not so long ago right here: https://rpgmaps.profantasy.com/overland-heatmaps-with-cc3-by-jason-payne/

It's nearly there roflo. If you erase around the edge of each of the cloud symbols in an uneven way (in GIMP/PS or similar app) so that there are no more sharp edges, and it should work a bit like a PS brush, but in CC3.

Solid 10 is a semi-transparent bitmap fill, which should already exist in the style template (if it doesn't, just shout and I will explain how to get it there). It's intended as a shadow.

That's interesting about the typo. Thanks for letting us now. I will notify Tech Support so that it can be put right for future users.

Type DELAYDRAWSYM and hit enter.

It should be set to 1 by default.

Type 0 (zero) and hit enter.

Then redraw.
