Problem with rendering a map
Every time I render this map the shoreline draw becomes hollow white but only like a strip across the whole map as highlighted by green. Any idea how to fix this as I've poured weeks into making this :(

Seems like something odd is happening at one of the rending passes. Try to reduce the number of passes, see this FAQ entry.
It reduced the passes, but made the problem worse. Now it does the entire costline that way
Could you post the .fcw file? I'd like to dig into your entities a bit.
So I did the opposite and increased the passes and that resolved the issue
Seems to be something weird happening here. I've asked the developer to take a look at it. I do understand you did get your export correctly for now from your attempt at increasing the number of passes?
Yes I set the exportsetupmppp at 3000000 and the error got smaller and then at 2000000 the problem went. Now it takes even longer to render sadly but it does work that way for now.
I talked to the developer, and it seems it is the complexity of the coastlines that is causing the problems. It's only 5000+ nodes, but it is a smooth polygon, which increases the rendering complexity of the entity considerably, to the point where it is causing an issue if too much of it is rendered in one go.
One workaround is to do as you did, reducing the size of the bands, creating more passes, but less complexity for each pass. You could also turn the coastline into a straight polygon instead of a smooth one, as this will reduce the complexity considerably, but this may or may not change the appearance on the final map (Well, it does change the appearance, it is more if the difference is really large enough to notice or not, you can't zoom into an exported image as far as you can the CC3+ map itself anyway.) Note that you also have a landmass poly below the coastline, which is just as detailed.
How do I change it to smooth? I may not and just bear with longer renders. It's not like I have to render lots.
To change it to straight, right click Explode
and pick the Smooth to Straight command to use on your poly. The process is also reversible with the straight to smooth option.
(Keep in mind that it will be easier to notice the difference inside CC3+ than on the exported image)
[When you convert the coastline to straight, you may notice a weird spike near the top left. This is caused by you going back and forth when placing the nodes, causing the lines to pass over each other and create a really sharp angle. I noticed it earlier, but the smooth polygon kind of hides it much more effectively than a straight one, so you may wish to go in and remove the offending node with Delete Node
. The node is located in the middle of the "cross" where the line spikes, not at the edge of the spike.]
Okay thx
Having changed the coast to straight it's working a lot better and also a lot smoother mapping experience. Only needed to remove a few spikes with little issue.
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.
It doesn't seem that different after the clear up of spikes. I left a few small parts smooth but other wise all straight and it seems just fine on render. Also the exportsetmppp being at 40000000 seems to work much better.
