So the islands are vanishing?

When you change the properties of the water you are also changing the properties of the magenta cut-outs. They need to remain unchanged.

Try starting from the state of your first screen shot and change the ocean again without picking the islands, or carefully deselecting them so they remain unchanged.

Or, if you have already changed everything to the other water fill, try picking the islands only and changing them back to magenta polygons using Change Properties.

Because those bits have been cut out on the water sheet they no longer exist to have properties changed on that sheet. If you want to change what you see through that hole you will need to modify the terrain you can see on the sheets that are revealed by those holes, and not the holes themselves.

What changes to you need to make to the islands?

Yes. You can import the scanned image into your drawing using Insert File in the Draw menu.

First, make sure the image you want in your map is in the same folder as your FCW file, and keep it with the FCW file from that point on.

Second, make a new sheet and call it BITMAP, or TRACE, and pick or create a new layer by the same name. Make sure both are active in the status bar.

Then import your image. A dialog will open allowing you to browse to the file. When you have opened it you will need to click once to place the lower left corner, and a second time to place the top right corner, thereby scaling it to the size you want it.

Finally, You will need to add a Transparency sheet effect to the BITMAP sheet to control how opaque it is.

Don't forget that you can move the new BITMAP sheet up and down the list to put it in the right place to prevent it getting in the way.

Have you got any other city styles you can use?

@Royal Scribe I tried that. It wasn't. Nothing seems to prevent it, or cure it.

By the way, Helen, I'm not saying don't report it to TS - just that the answer may take a bit longer than usual.

I used to drink gallons of the stuff to stay alert at an office job. Now I'm coffee-total.
