No, CC3+ doesn't have a way to create a gradient, you'll need to use an external raster file as a fill or a symbol.

The default symbol sheet isn't a global default, but rather a per-symbol setting, allowing CC3+ to be set up with different symbols on different sheets. The default sheet for a symbol is stored individually for each symbol in the symbol catalog. To change this you need to edit the symbol catalog by loading it in to the main editor (as a map) instead of in the symbol catalog window. You can now open the symbol manager, and from there access, the properties of the symbols to change their sheet.

Note that I do not recommend you edit this, rather, take advantage of the naming scheme for sheets. Most symbols are set up to go to the SYMBOLS* sheet. Notice the asterisk. That basically means that if the currently active sheet starts with the text SYMBOLS they will be placed there, but if it doesn't, they go to SYMBOLS. You can take advantage of this and name your sheets things like SYMBOLS SECRET, SYMBOLS HIDDEN and whatever.

The layer setting is controlled by the symbol catalog setting, and is set when you load in the symbol catalog. You can see this setting for each of your catalogs by clicking :CC2SYMICOND: then clicking Advanced. Now pick any symbol catalog setting in the list and then click properties to control what layer that catalog uses.

Note that there isn't a single default scale for symbol that will work for both these sets of symbols, as these are not scaled in relation to each other. When mixing two different types of maps like this, you'll basically have to do a little work and experiment a bit with what scale works for the city symbols and for the overland symbols individually, and make a note of these two scales (hint: store it in a map note so it follows the map).

Exactly. Tokens are used on a map during play, they aren't normally part of it (except as the odd decoration). Downloading a png map image from the atlas with tokens pre-placed in the image would make it useless as a battle map.

I guess if all the tokens are placed on their own sheet that can be hidden, and I am notified of it during submission, I can set up one of my toggles in the nav menu. That way the map can be displayed without tokens by default, but users of the .fcw can hit the link to show them.

Best way to handle that is to make sure the layer the grid is on is frozen. That's usually the HEX/SQUARE GRID layer.

• Yes. Anything you do in-map (using allowed resources) is perfectly fine. The main thing here is that you cannot find your own symbols/fills from outside the allowed resources, because this causes distribution problems for the atlas.
• Yes, that is fine.
• Yes. I usually prefer to have these on different maps, because CC3+ can really only maintain one scale in any given map file, but there are cases when things work best together.
• Nothing against tokens directly (as long as they adhere to the allowed resources), but generally having monster tokens on the map makes the image export a bit weird, anyone downloading just the png file from the atlas would have a image file with immovable tokens.
