Most of the islands do not have road generation

[oddnoises]

If I set the IslandRoadPercentage = 100 roads should be generated on all islands, according to the docs, but in all cases roads are generated only on a small part of the islands.
The screenshot shows a freshly generated world (solo game, seed nRleKzu9bI) with default configuration except IslandRoadPercentage = 100.
I understand that some islands may not have key objects for generating roads, but at least they should be generated for all bosses.
I tried to set

CustomLocations = Eikthyrnir,Dragonqueen,Hildir_cave,Hildir_crypt,GoblinKing,GDKing,Bonemass,Vendor_BlackForest,Hildir_camp,BogWitch_Camp,FaderLocation,StartTemple

parameter, but that didn't help either, and most of the roads aren't generated.

similar issue here. for instance the last world i generated, i had percentage set to 100, all vanilla POIs and MWL POIs added to locations, PR is detecting 80 islands but spawning only 24 roads.

@oddnoises @literallybyronic Hey friends, so actually the IslandRoadPercentage config is a bit confusing. It doesn't actually mean that you are guaranteed to get roads on all those islands. It just means that the mod will attempt to place roads on that many islands. I've explained this a bit better in the newest version of the mod.

The thing that is more likely causing less roads is the max attempts to find a path for each road segment. I've increased the default value of this and also added a config so you can tweak yourself. Let me know if this config helps at all!

@literallybyronic @oddnoises Also, regarding the custom locations. I have seen a few reports about this not working right. I didn't have time to debug that today but will look into that next!

yep, increasing the iterations did the trick. gotta play around with it to figure out what my ideal settings are gonna be but i tried it with 20k iterations instead of 10k and got like 50 or so roads, as opposed to the 20-something i was getting before. i wanna get it set up so that it will actually generate road networks that feel more natural instead of single A>B roads few and far between. it does increase initial worldgen time but tbh i don't really have a problem with that since once i get the settings nailed down how i want them, i'm not going to be doing it super often, and i can just walk away and grab a snack or something, or watch a video while i wait.

custom locations are working fine for me it seems, although I only added the ones from your More World Locations, but they're definitely showing up as destinations when i generate the pins.

[oddnoises]

Tried to set the PathfindingMaxIterations parameter = 100000 and generate a world with the same seed as it was originally. There are a few more roads, but for some reason most of them are located on the edges of the map.
It may be worth adding an option that will allow to add custom pins that will emulate key locations, which will increase the probability of successful road generation.

So I did some messing with the iterations and it seems they stop making much difference at about 30K. you can watch each one being generated in the console during worldgen and they don't seem to go over 30K or so even on much higher settings (100K). not sure if this is just running up against max island size or what.

Even at 100K iterations it's definitely not utilizing all or even most POIs on an island though. with MWL there are tons of them and i have them added to the custom locations but i'll still only get 2-3 roads per island max. wondering if there's a limit on choosing POIs on the same island that could be increased?

Hey @oddnoises & @literallybyronic - I did some research on solving this issue as I was running into it to. Take a look at PR #29 (even just the maps) and see if it addresses your concerns.
