You're welcome :)

Remy wrote a really nice blog that contains all the information anyone might need on managing colour palettes if you are interested here:

Hi Cal :)

The colour palette has changed for some reason.

This is the palette attached to a new MD map:

And this is the palette attached to your map:

I saved the custom palette from the new MD map and reloaded it in your map. Then attached that palette to your map and here it is:

That looks like transparency acne, which happens when the pixels in overlying polygons are identical in colour to those of the underlying polygons. It confuses the rendering engine into thinking there is nothing there in that particular pixel space.

When you have sheet effects that modify the appearance of the edge, they will also affect the edge of all these 'pinholes' as well - hence the spotty appearance. Each pinhole gets a bevel.

The easiest way to deal with this is to change the texture in the WALLS sheet polygons to make it different enough from the background fill that this doesn't happen.

Or...

You can make a backing sheet to separate the two grey tones that are causing the problem using a third colour that isn't related to either of them. You do that by creating an exact copy of the WALLS sheet but with the texture turned to a solid unrelated colour (I used purple in the example below). I copied the Color Key across to the new sheet to cut identical holes in it.

When you make all the sheets visible again it looks no different to before because the purple is entirely hidden by the original WALLS sheet, but when you export it those pimples will be gone.

It will be easier for you in the long run to change the texture of the walls polygons to a different one so you don't have to mess with the BACKING SHEET every time you want to adjust the WALLS sheet, but in case you are fixed on those two greys you can have the one I made.

I think you should do what you want to do.

If you are anything like me, I start something, then realise I should have done it some other way, restart it the other way, then realise it was better the first time around and go back to it. The best things happen by trial and error.

Hi everyone! :D

This week, Ralf will be creating a zoomed-in regional map from an existing larger one.
