Hi tafferka :)

That's down to your Maximum Pixels Per Pass settings.

When the image is rendered CC3 does a number of passes from side to side across the map that are as deep as permitted by the MPPP value. When the source of an effect lies outside the current pass CC3 is unable to 'see' the effect itself, so a pool of light is cut off with a horizontal band.

Type EXPORTSETMPPP on your keyboard and hit Enter. Check the command line to see the current limit. If you haven't used this command before now the default is 4000000 (4 million). You can now add a zero and multiply it by a factor of 10 by typing 40000000 (40 million) and hitting enter.

Hopefully, this should cure the problem. Please let us know if it does not.

It is basically a good map, though you are missing a scale bar.

The one thing that may need a bit of tweaking is the placement of trees. What is the map telling us? I get the message that this is either dense jungle and covered all over by trees that are represented by the spaced out single trees, or that there are remarkably even copses of trees, each symbolised by a single tree. Since I don't know the scale I can't be sure which of these may be true.

If your area is only partly wooded (for example a forest that has been eaten into by agriculture, or which has large clearings of grassland) it may be communicated more effectively by creating clumps of trees as wooded areas.

Take a look at other maps and the way that other people have shown forest and jungle. If you think a different method might portray your area better, it may be time to reconsider the tree placement.

This is to do with extreme altitudes and data that isn't a number - Outliers and NANs.

The instructions on how to ensure your world is free of them are the last 2 paragraphs on page 10 and all of page 11 of the Supplemental Notes.

With hindsight I maybe should have put this in the main Mapping Guide, but at the time I didn't think these things affected unedited synthetic worlds. Isn't hindsight a wonderful thing!

I wouldn't say that was mundane!

You're like me, and lots of other people as well. We got on with life and made stuff along the way in those odd moments of time between all the busy stuff :)

Thanks for sharing!

There isn't a public list.

Once I start work in earnest on a new project the list has already been agreed between myself and Profantasy - if there is a need for one.

The list I have for Spectrum Part 2 was made before I started drawing any of it - a combination of requests and preferences from forum and FB Group members. The problem with publishing it, though, is that doing so is like asking for more suggestions when the list is already full, and has already been balanced and agreed upon with Profantasy.

So... no list. Sorry!

If there are lots of requests after Part 2 has been published - that will be the time to make suggestions again ;)
