Hello Chronist
Before you even start incorporating new textures into your maps that are not either part of the Profantasy set, or don't come with specific installation instructions like the CSUAC or Bogies Mapping Objects, the first thing you need to do is make a new folder called 'User' (or your name) in the right place to hold all the fills that you as a user want to install. This new folder has to be inside the 'Tiles' folder, like this:
C:\ProgramData\Profantasy\CC3Plus\Bitmaps\Tiles\SUE
The exact path to your Tiles folder may differ slightly from the example above if you didn't use the default settings when you initially installed CC3+, but once you find the Profantasy folder the rest should be the same from there.
In practice it isn't good if you have too many textures all in one folder, so I have upwards of 20 subfolders within my SUE folder. These are called things like 'Terrain', 'Vegetation', and 'Water' and have immediately obvious contents. Since your working methods and the type of map you want to create is probably quite different to mine, you might want to classify your fills into different groups to the way I have done it, using a different classification system. That's totally fine, as long as you classify things right from the start and don't try to move things around later on.
The reason all these files and folders need to stay where they are in relation to one another once you have started using the fills they contain, is that a CC3 map will 'lose' a fill that's been moved after you loaded the fill into the map.
Because of this little problem with having to leave stuff exactly where it is if you want to be able to continue using your older maps, its worth spending a bit of time deciding on your classification system and naming your subfolders before you even start downloading the textures that will eventually go inside them.
Give me a shout when you've done that, and I'll write the next step![]()
