Inspired by Herra Tohtori's post on improved skyboxes (which look awesome, by the way), I decided to experiment with creating some variations. After downloading the .7z file on his highlighted post, I swapped out the skybox textures in PCS2 and made a ridiculously simple mission with FRED to test it. However, when I started the mission I was greeted by the default background, that being the black boring void of space. Depressing. (And yes, I selected the skybox I wanted in the FRED background editor, so I know that's not the problem). I suspect that there's something wrong with the texture format I'm using (one .png pic for each side of the cube), but I'm not sure where to go from here. Help (and thanks in advance), anyone?
