That white line is a guideline that shows where the actual nodes are for smooth entities.

I wasn't suggesting you use the actual ferraris fills, just pointed you to that style to show an example of how it can be laid out.

I guess the fills do work out there though, but I would seriously lower the scales of the fills, they're way to large the way they are now. Also, aligning the fills to follow the road (or something else) will give a more organic look rather than have them all perfectly horizontal. If you look at the ferraris style example I liked to, it also uses rows of threes/bushes on the border of the fields. This both looks good, and is often done in real life too.

CA50 is from volume 5, yes.

The bug should be fixed now. I had a function for getting the root of the file name that naively expected the only period in a file name to be the separator between name and extension.

The full color logo is actually quite nice, it gives the impression that this piece was important to get right, and warranted more attention.

You're really into making this garden leafless?

The resolution during export is the same as on screen, it picks the appropriate resolution based on the actual size of the symbol in the image. You can force it by selecting Very High before exporting, but it shouldn't normally be needed, as you won't get a benefit from using the very high symbol as a base if it is only going to occupy 10px in the final output anyway....

Ah, I see. It is just the name of a tool from that style. I don't really know the purpose of it, but it is just drawing a regular polygon. Mayby it is intended for drawing polygons that you can later use a cut operation against, but there isn't anything cutting or cutted in the tool itself.

Great it worked out for you. Smooth polys require more computer resources to render, so avoiding them on complex entities is preferable, but of course, depending on the map, one may want the slightly nicer look.

No, inlays.
