I don't know if this has been stated before, or if it's just common knowledge that I recently figured out on my own, but I thought that I should share this little tip for the good of the community.
As we all (or, as most of us) know, when you set up the build game screen for your impending awesomeness, the skybox refuses to change, including the ambience, if you should so decide on a different skybox for your level. And it bothered me so much that I had to figure out how to get it to change and stick WITHOUT altering the setup.ini file manually. And here's how I did it.
I started my game level and it used the skybox that was the currently set sky. I then changed it, and nothing happened (which was completely expected). So I started a new level (File, New), and then changed the skybox to what I wanted (in this case, cty). I set a ground tile and a player marker and clicked Test to make sure that the skybox worked. It did.
I then loaded my game level, complete with its own setup.ini file that was already set with the cty skybox I wanted to use. I clicked test, and...bingo! The skybox worked.
I tried this as a test several times, changing the skybox multiple times (as well as the ambience), reloading my game level after each change to make sure it stuck. And it does.
This is a round-about work-around for this, but it does work. And I just wanted to share this with the community. Although, hopefully, this will get changed in an upcoming release of FPSC.
