Thanks Wyvern. Here's the maps in the atlas.

That's the standard for all images in the atlas. I export them without a grid so people can use them in VTT's. An existing grid grid in the image often makes issues. Since you cannot turn on/off the grid in an image like in the fcw, I find the gridless versions more versatile for the image (and no, I am not going to publish two different versions of the images on the website).

For users of the actual atlas, they can just toggle it in the fcw.

The square is still there because it wasn't on the GRID sheet. (Which is actually fine, because a visible square helps VTT users to tune the in-software grid.)

I haven't read the text from the annual issue, but if the instructions feels unclear, don't hesitate to give Ralf a word about it. There are many people reading those things that don't hang around here.

I do mostly agree with JulianDracos and Kertis Henderson here. 1TB drive/16GB ram is fine, and as Julian says, a fast processor is better than a slow one with many cores, although a certain amount of cores is highly useful (I recommend 6 or more, but most CPU's will fulfill that today)

As for the screen, I fully agree with Kertis, don't get a 4K one. I used to have one on my old Work laptop, and it was a pain for most things. I prefer to go a bit higher than a full HD (1080p) screen though, I find a 1440p one much better. But there are two factors here, first of all, your eyesight, 1440p naturally makes things smaller (and buying a 1440p just to increase the scale factor in Windows is a waste), so make sure you're comfortable with the size, otherwise do go for that 1080p one. And of course, a higher resolution screen do mean CC3+ is a bit harder to run, so it should only go along with a somewhat good CPU, if you go budget on the CPU then do not get a 1440p screen.

My own laptop is a Lenovo Legion Pro 5 (1TB/16GB/i7-13000hx/RTX3070/2560x1600), a machine I find well suited to most task and pretty good value for money.

You need to use the right house tools. There are separate house tools for metric (the SS5C m ones) that uses frills that are scaled for metric maps.

This is an unfortunate bug with some of the vector symbols when you have CC3+ running on the Arm platform. CC3+ is a using the x86 instruction set, so when running on the arm cpu, there is a compatibility layer that translates the instructions from x86 to arm, but unfortunately, something goes wrong.

It is the same issue as you experienced here: https://forum.profantasy.com/discussion/13970/pete-fenlon-revisited-symbols

Unfortunately, there isn't anything we can do about it right now. I recommend staying with styles that use raster (png) symbols for now.

This is more or less what I am doing in my dynamic dungeons project. Unfortunately, I haven't been able to pick it back up in a long time, but it still exists as a proof of concept for this functionality. Hopefully I can finish it one day. There is a video showing it in action linked from the beginning of the article:

Sounds like an interesting idea. While I have no idea if something like this will be made for CC4 or not, you can already today get access to all the data needed, so that should be able to be done with an add-on, meaning even if it isn't put into CC4 by default, it should be possible to write for anyone with a bit of programming experience and put in without PF having to add anything to pave the way.

The technique Ralf showed here unfortunately only works with bitmap fills. This covers most maps, but some maps, especially maps using line-work (like the landform maps) use different techniques for the fills.

It gets a bit more complicated to scale these. I am pretty sure Ralf showed that off in a video at some time too, but I don't remember which off the top of my head. I'll see if I can find a link for a video or something else, unless someone bets me to it.

If you try with for example the Mike Schley overland style, you'll find that this trick works the way Ralf showed it if you use it on a bitmap-filled polygon, like farmland for example.

For sharing, yes, it is completely fine. The only things that matters when sharing the file is that the recipient have the actual art files on disk. You can make as many fills as you want inside the map without that being a problem, sharing issues only becomes an issue if you manipulate the png's on disk (such as making copies of them). As long as you can see inside that fill style dialog that both versions point to the same png files, then everything is fine.
