I am running tests on the terrain generator today. One user has encountered a terrain generation error.
So this new error seems to be very rare, and will only effect larger planets most likely, and then only if your max terrain size is set higher than 14 or so.
You can avoid this by limiting your max terrain size to something around 14 or lower, but you may still encounter it.
I have created an automated script in my build of the game that generates terrains automatically, and lets me know when these errors are encountered. So far it looks like it can detect the errors successfully.
If I can detect them, that means I can prevent them from loading in-game. Once the script detects such an error, it will flag it, and restart the terrain generator. This kind of thing already happens, and sometimes you might see the loading bar jump back when you are landing on a planet for the first time.
Basically, that means the terrain generator cannot successfully build that terrain, so it starts a new one. Its a bit inefficient, but it gets the job done, or so I thought!
Anyway, once I have a little more confidence that this new script is actually working, I will update the game. I am hoping to have somehting by tonight, but maybe by the end of the weekend if I can't do it sooner.
