Make a folder called User in the Bitmaps folder here:

C:\ProgramData\Profantasy\CC3Plus\Bitmaps

Then put your png fill style in that folder and import them using Import bitmap fill styles in the Tools menu. You should then be able to pick them in the Fill Style Properties dialog and use them as polygon fills.

I had one of those, but it died when Win 10 came along.

You do it better than I can, Ricko :)

Well done :)

It works to a point, but it looks better if you put the ones that go around the top of the shape on a symbols sheet underneath the terrain fill. That's what I did with the example map. It's a bit fiddly, though.

No, it's perfectly correct.

The forest drawing tools in the published version all draw much better forests than I had designed.

If you check the fills you will see that there are 5 forest textures I made. Originally, I also made 5 forest drawing tools that used those textures, placing each one on a sheet of its own to allow them to be blended together using Edge Fade Inner on each one.

The drawback to this technique is that even though you can draw whole forest worlds really quickly, every edge has to be carefully decorated with single trees to bring the forest to an end. There is a small example patch of textured forest in the example map I made.

So this is more a case of the artist designing things one way, and the publisher realising there is a much better way of doing things, while leaving the artists original sheets and textures in situ to allow people to chose how to do their forests.
