Yes, you can scale the fill. I am assuming here that it is a bitmap texture fill you are using.

Click the last mini window on the bar of them across the top of the app, where it will have something that starts with "FS:".

This will open the Fill Style Properties dialog.

Select the Bitmap Tiles tab, and then pick the texture you want to rescale from the dropdown box called "Fill Style Name"

Once you have the fill picked, look down a bit and you will see 3 boxes that control the scale of the fill. Make sure the first box is checked, and adjust the scale of the fill in the width and height boxes next to it. Ok and see what you've got.

In most styles the scale is in map units, or in feet/metres depending on which template the map is based on. If you only have one tile per 5 ft square and the scale is currently "20", and you want 4 tiles per square you would need to reduce both scales to "5"

As it turns out I just didn't read the exact details of your previous comment correctly myself, or I would have realised that anyway.

Good that you've solved the problem though :)

You keep safe now, Jim!

We're always here :)

The settings are all available in the FCW file you can download from the blog page. You could open that alongside your own map and use copy and paste to copy them to your own map.

The effects are tuned to work with the textures used on that sheet each time, so you might want to use List from the Info menu to find out what those fills are. They will all be CD3 fills, so you might want to create an empty CD3 map and import it and then undo the import, just to import those fills with relative ease.

There are whole cave systems full of both stalactites and stalagmites that have since been drowned, so I wasn't worried about them being in the water at all.
