There's a Buddha-like figure in part 1 made of white marble, and the second one shown above is a fox.

There are no smaller symbols of that kind in Japanese Temple or Asian Town because it is a city style, and at that scale most statues would be really tiny - the foxes certainly.

However, I will have a think about how to sort some of these limitations out in the long run.

Working on the statuary a lot of people asked for.

Thanks Joe :)

Another thing that might be affecting the export is if you are using less than 85% JPEG Quality. Some of that pattern reminds me very much of the kind of artefacts you get when exporting low quality jpegs.

If you click the fill style box and open the Fill Style Properties dialog, then pick the Bitmap Files tab and select one of the troublesome fills you should see that it is Scaled and that it has a set Width and Height.

(Sorry about the jiggly red lines - my hand is a bit shaky, as I have Covid right now and I'm not terribly coordinated at the moment)

To make the fill appear larger in the map and reduce that pattern a bit you could increase the dimensions in those boxes. As with all things, though, there is a limit to how far you can push it like that before you get pixilation issues.

It's the same scale in CC3 as it is in your export. The appearance may differ a lot, though, depending on the size of your export.
