You need to have your skyboxes in a specific naming format in order for them to work in FPSC.
Look in your SKYBANK folder for examples, because that is where your FPSC skybox folders should be placed.
The first thing you will notice is a 3 letter format for naming the folders.
If you use more letters then it won't work.
I made a utility for creating the skybank folders for your custom skybox images using DarkBASIC Professional.
It is free, so you are welcome to use that if you want.
Just search 'ceSky' or look in the media section of my website for the download.
It is a pretty straight forward program and nothing fancy, but it will convert your six images into a proper FPSC skybank folder for you.
Just drop the exe in the folder your images are in to avoid typing a full path for the images.
The instructions are included.

It would be TPSCreator then, because it wouldn't be First Person perspective anymore.
So NO, you need DarkBASIC Professional or the Dark GDK for that. (involves programming)
