Thanks, Morrgans :)

I came up with a solution for this map, but it might only work for this particular map, and it might break as you continue to add more details. It depends very much on where you go from here, but we can look at it again if necessary.

I created a second WATER sheet, called WATER (sea only), copied the sheet effects across from WATER, then copied just the sea parts of the water to it. This was to preserve the rivers and marshes. Moving them down the list by moving the original WATER sheet did bad things to your map.

Then, because CC doesn't react well to having the exact same shape with the exact same fill on different sheets I changed properties on the original sea polygons on the WATER sheet to a solid grey colour, knowing that they would be entirely covered by the new sea polygons on the new sheet.

However, even though at first glance it all looked great, zooming in to the coastline revealed that the rivers were now blocked by black lines - the dark glows on both WATER and WATER (sea only). So I removed the dark glows from the new WATER (sea only) sheet, and added a series of Edge Fade, Inner sheet effects to it so that the black line effect from the underlying (and now grey) original sea polygons on WATER were visible just around the edge but without revealing the grey polygons.

I had to move the deep water down so it still appeared on top of the new WATER (sea only) sheet.

Summary:

The original WATER sheet is exactly where it was but only has the rivers and marshes on it, with a grey copy of the sea. The WATER (deep) sheet has been moved right down the stack to stay on top of the new WATER (sea only) sheet, and I've moved the TEXT water names sheet down for the same reason - so the labels stay on top of the sea.

As I said at the outset, this is a 'here and now' fix and might break. But if it does cause problems as you map more details, shout again and we'll have another look at the situation.

Thanks :)

There's no actual error as such involved.

The template for this map is CA177, which is Darklands City.

When you add a House entity from a different style, like CA183 (Winter Village), the map lacks the bitmap fills it needs to fill the roof parts. The missing fills are replaced with solid colour polygons instead, which shows as dark grey and black in one building, and white in the other.

The reason the two black rectangles are slightly different shades is because they are two sides of a single roof which has been shaded so that the side facing the global sun direction is lighter.

If you draw a house in the default style for this template (CA177) you will see what I mean. In this shot I've increased the resolution so you can see the tile texture clearly, as your existing houses were quite large.

Although the ones you've already drawn can't be helped, you can draw CA183 houses in your CA177 map if you import the necessary fills.

First, create a new map in the CA183 style - a temporary map. The CA183 style template is called "Winter Village"

Then reopen the map you were working on and import the temporary Winter Village map into it using Draw, Insert file... Don't paste it, though. Just press escape. That will have imported all the necessary fills for you.

After that it will be possible to draw Winter Village House entities in your Darklands City map.

I've saved the version with the Winter Village fills here.

You can make the effects stay on for that map by opening the Display Speed Settings dialog|CC2RESMODE| and checking the Effects are on when loaded box. Save the map after you OK that setting.

EDIT: Most recent templates have that setting checked by default. It's only the older styles where it's not turned on.

As Don suggested above, sheet effects would help a lot as well. Before adding any more sheet effects, maybe check first that the Activate Sheet Effects box is checked in the Drawing Sheets and Effects dialog |CC2SHEETS| so that any effects already on the WALLS sheet will appear. I suspect they might not be active, since I can't see any shadows or glows in the shot you showed us.

The Ferraris Style isn't the simplest one I ever made, so it does take a bit of working out if you are trying to learn from the example map.

Here is the map with just two sheets showing - BACKGROUND, and WATER.

And here is the same view showing the TERRAIN salt marsh 1 and 2 sheets, without the water.

It is a very long time ago (for my memory) since I drew this map, but I believe the water was drawn first using the River, Default straight drawing tool.

Then the mud was drawn around the rim of that water using the Terrain Default, Mud drawing tool. (I've drawn a quick example to the right of the actual marsh)

Then the islands were drawn last, using the Terrain Default, marsh island drawing tool.

So there are 3 drawing tools involved in creating this marsh area with it's muddy banks and marshy islands. There aren't any multipolies involved. I try to avoid them at all costs - even in the more advanced styles I make. The appearance of holes might be due to the fact that you need to refresh the view? I don't know why it gave you that impression.
